Parent class: VirWare
Viruses and worms are malicious programs that self-replicate on computers or via computer networks without the user being aware; each subsequent copy of such malicious programs is also able to self-replicate. Malicious programs which spread via networks or infect remote machines when commanded to do so by the “owner” (e.g. Backdoors) or programs that create multiple copies that are unable to self-replicate are not part of the Viruses and Worms subclass. The main characteristic used to determine whether or not a program is classified as a separate behaviour within the Viruses and Worms subclass is how the program propagates (i.e. how the malicious program spreads copies of itself via local or network resources.) Most known worms are spread as files sent as email attachments, via a link to a web or FTP resource, via a link sent in an ICQ or IRC message, via P2P file sharing networks etc. Some worms spread as network packets; these directly penetrate the computer memory, and the worm code is then activated. Worms use the following techniques to penetrate remote computers and launch copies of themselves: social engineering (for example, an email message suggesting the user opens an attached file), exploiting network configuration errors (such as copying to a fully accessible disk), and exploiting loopholes in operating system and application security. Viruses can be divided in accordance with the method used to infect a computer:- file viruses
- boot sector viruses
- macro viruses
- script viruses
Class: IRC-Worm
This type of worm spreads via Internet Relay Chat. Like email worms, IRC Worms have two ways of spreading via IRC channels. The first involves sending an URL which leads to a copy of the worm. The second technique is to send an infected file to an IRC channel user. However, the recipient of the infected file has to accept the file, save it to disk, and open (launch) it.Read more

Technical Details
This is a polymorpic worm is written in Batch script with the extensions Windows 2000/XP (cmd.exe). The worm contains two parts: polymorphic generator and main body. The polymorphic generator reconstruces the main body on each start of batch file. The worm creates its droppers with the files: SPTH.BAT and C:MIRCSATURN.BAT. It also creates the script file C:MIRCSCRIPT.INI. The script sends worm dropper (SATURN.BAT) to each user who joins the infected channel. The worm also rewrites batch files into WINDOWS directory. The worm contains the comments:
----------- BatXP.Saturn ********** by Second Part To Hell ----------- | I think, you are looking at the code and think: "What the hell is this?"| The answer is: A Windows XP Batch polymorph virus :D | WinXP is using a program named CMD.EXE instate of COMMAND.COM for DOS | You're able to make the really nice things with CMD which you wasn't | able to do it with COMMAND.COM. | | Information about the virus: | Virusname......................: BatXP.Saturn | Virusauthor....................: Second Part To Hell | Size...........................: The poly-engine has 1.301 Bytes | The whole virus has 4.158 Bytes | Encrypted......................: Yes, but only the virus part. | I'll crypt also the poly engine in | next versions. | Polymorphic....................: Yes | | written from 20.11.2002 to 22.11.2002 | in Austria | ----------------------------------------------------------------------
