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
Any program within this subclass can have additional Trojan functions. It should also be noted that many worms use more than one method in order to spread copies via networks.

Class: P2P-Worm

P2P Worms spread via peer-to-peer file sharing networks (such as Kazaa, Grokster, EDonkey, FastTrack, Gnutella, etc.). Most of these worms work in a relative simple way: in order to get onto a P2P network, all the worm has to do is copy itself to the file sharing directory, which is usually on a local machine. The P2P network does the rest: when a file search is conducted, it informs remote users of the file and provides services making it possible to download the file from the infected computer. There are also more complex P2P-Worms that imitate the network protocol of a specific file sharing system and responds positively to search queries; a copy of the P2P-Worm is offered as a match.

Platform: Win32

Win32 is an API on Windows NT-based operating systems (Windows XP, Windows 7, etc.) that supports execution of 32-bit applications. One of the most widespread programming platforms in the world.

Description

Technical Details

Togod is an Internet worm spreading in the KaZaa peer-to-peer file sharing network. The worm replicates by copying itself into KaZaa shared folder.

Togod is a Windows application (PE EXE file) about 100KB in size (compressed by UPX, the decompressed size is about 175KB), written in Delphi.

The worm copies itself to the KaZaa directory using the following names:

The Togod worm then displays a fake error message:

 Error
  Error loading RCDATA

The worm also creates a randomly named EXE file in the Windows directory where it writes the code for "Backdoor.Lithium" and executes it.

Togod also contains the text:

 Hello to all the av's i hope to god norton doesnt detect this first... that would be sad.
 Hell yeah kaspersky!
