- Virus Name : KRiLE v1.0d [Experimental B-Depressed]
- Virus Target: .EXE and .COM *multi-os* (see below)
- Virus Size..: 5504 bytes.
- Target OS...: KRiLE is a multi-OS virus. Meaning, any .EXE or .COM file
- on Win3.x/MsDos/Win95/WinNT/Os2Warp are capable of not
- only being infected, but still operating as if nothing had
- happened.
- Virus Info..: KRiLE is an HLL virus, which makes use of some pure ASM
- functions included for size and speed. Since KRiLE is an
- HLL, it provides automatic shielding against hueristic
- analysis, but does not in any way damage KRiLE's ability
- to spread. KRiLE is system friendly in the sense it will
- avoid the following files to prevent any possible system
- lockups and/or program failures, which could lead to the
- premature detection of this virus.
- [command.com, start.exe, emm386.exe, mouse.com(exe),
- mscdex.exe, setver.exe, dos4gw.exe, explorer.exe,
- smartdrv.exe] KRiLE accesses files in a network or
- multi-tasking friendly manner, so as not to cause failure
- loading programs, which could tip the user to a possible
- virus related problem. (please see the section How KRiLE
- infects below for more detailed information)
-
- Encryption..: The entire KRiLE virus and files it infects are/will be stored
- in an encrypted format.
-
- PayLoad.....: Good viruses usually contain some form of a payload. KRiLE is
- no exception to this rule! KRiLE contains a siren effect
- which it might trigger before control is passed back to the host
- or it may decide not to trigger. KRiLE also contains a short
- encrypted message to infected users, and AV. :) This
- doesn't imply that KRiLE should be considered a good virus
- though. Some people will baulk because it's not pure ASM.
- Oh well, can't please everyone.
-
- Stealth.....: Some stealth is performed to keep the executing file from
- noticing any changes. As memory-image checking files are
- rare, this method should be fine. In fact, I have yet to
- find one program which will detect it has been infected by
- KRiLE. (I've infected all kinds of files for testing
- purposes. I even infected f-prot v2.28. <g>)
-
- How does KRiLE infect?
-
- KRiLE is a direct action prepending virus. This said, it will randomly choose
- based on how many directories were found via PATH statement to scan for
- victims. Once it chooses a directory, it will decide to infect between 1
- and 2 exe/com files inside that directory. This version of KRiLE attracts
- less to NAV and TBFILE if they happen to be resident, by renaming the file
- just before infection to some odd name (not exe/com), this way, resident
- scanners won't report modifications to Exe/Com files. We restore the filename
- right after :)
-
- KRiLE contains minimal bait-file avoidance programming. Basically, the
- only exe/com files KRiLE will consider to be bait and not bother with
- are files which are not KRiLE's size or larger.
-
- KRiLE also polls for checksum files created by Thunderbyte, CPAV, MSAV and
- VSAFE. If these files are found, they are quickly destroyed. VSAFE if loaded
- will be bypassed during the execution of KRiLE. The infected user will not
- be aware of any of this. KRiLE doesn't currently poll for NAV checksum files
- since I don't have NAV to study. If this turns out to be something important
- I'll add it, otherwise, I don't care.
-
- Although a win 3.x series (NE) file can be infected by KRiLE, it will no longer
- run properly unless it's run under Win95/NT. If you run an NE file on win3.x,
- KRiLE will still spread, but shortly after executing windows will say this
- file is not windows based. This problem does not occur on win95/nt or os/2
- based operating systems.
-
- This virus is well armored against heuristic scanning and repair. Thunderbyte
- Anti-virus is tricked into corrupting an infected file if you attempt to
- use TBCLEAN. KRiLE has been tested against the following anti-virus
- programs: FPROT, AVP, FINDVIRU, MCAFEE, NORTON, and Integrity Master.
-
- KRiLE has been tested against TBSCAN v8.03, The only flags triggered:
- c?. Hardly enough to warn or scare a user :)
-
- Greetz:
-
- [SLAM] - This is KRiLE 5.. The most advanced one so far. Well advanced
- as an HLL can be. This may also be the final KRiLE, and possibly
- the last virus i'll be writing due to problems in RL. But who
- knows, I am consumed with writing them... Maybe, I'll write some
- more just to piss off certain people.
-
- #Virus - As one of you mentioned, I'm consumed with writing my "Shitty"
- viruses. And if you don't like that, Too fucking bad.
- Not everyone writes viruses just to say, "Yea I did it" I write
- them for the sole purpose of wreaking havoc. Those of you who
- have (heh) morals, FUck you! I don't give a flying fuck who I
- infect. The more the better. Those of you who don't like this,
- probably shouldn't be coding or being in #virus to begin with.
-
- Microsoft - Blah, Your OS sucks balls
- Mcafee - Still sig based scanning? Blah..
-
- To all VX related:
- Those of you who think my viruses suck, Oh well. I really don't care
- what you think. Those of you who think i'm an asshole, Good. I don't
- care who or how many scum sucking lamers i infect. I'm doing the world
- a favor removing dipshits like that.
-
- To all AV related:
- Blow Me. I'm coding more of these fuckers then U shitheads know what to do
- with. Go ahead, put it on some auto analyzing machine. hehe
- Except this time, atleast TRY to get your "Virus Description" information
- right. It's annoying looking over your work, counting your pathetic errors
- and for once, Wise up, These viruses aren't going to go away Just because
- you don't name them as what they are. Lame asses.
-
- VX Ezines are welcome to publish the exe and/or this nfo file if they want.
- Source code will no longer be given out. You already know what it looks like
- anyway. And if by some small chance you don't, Find someone who has older
- source code to look at. Get a good laugh out of it. Hell, I laugh
- everytime I infect someone.
-
- This is also an experimental KRiLE.. as such, it might fuckup on occasion.
- Too bad.
-
- Revision History:
- KRiLE v1.0 - First KRiLE on the scene, Used old internal decryptor and
- LZEXE to maintain compression. Was easily caught and payloads
- went off often.
- KRiLE v1.0a - Second release, Minor bug fixes, experimental crypto engine.
- KRiLE v1.0b - Added randomness for dirs and files, trying to speed it up
- changed compressor again.
- KRiLE v1.0c - More randomness, added code to try and avoid tbfile/nav, also
- changed compressor/encryptor and various encryption sequences
- withen KRiLE. KRiLE uses about 30k less then all previous
- varients, due to more efficient coding and change of
- compression. Occasionally, Previous varients would infect
- files that they shouldn't have. This has been corrected.
- KRiLE v1.0d - Streamlined encryption/compression yet again. (seems I'm always
- fucking with this part) Added a special Fuck U payload. And
- made this version of KRiLE a bit smaller then the last, By
- 350 bytes or so. Changed docs a bit, to reflect my mood.
- If anyone is pissed off by this, Waaaa.
-
- Yea KRiLE isn't a real speed demon either, so i'm told. Although, I did
- infect some stuff on a Cyrix 166 and it was instant (under win95). So,
- I don't know wtf you guys are running. Hell, it ran fast on a p100.
- Basically, if your just going to bitch about how slow it runs, FUck U, I
- don't want to hear it. Code something better then.
-
- Send me your hate mail, complaints, comments etc! I'd like to read what
- you have to say about this or any other virus of mine. Don't email
- asking for source code. I've already sent the source code all over the
- place, Look around for it. If you know where to look, you can find an
- email address for me. Is whatever you have to say worth it? :)
-
- By all means, use whatever methods you know/can to spread this virus into
- as many unsuspecting users as possible. If it means taking a network offline
- fine by me. A local BBS will provide some entertainment :)
