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: Virus

Viruses replicate on the resources of the local machine. Unlike worms, viruses do not use network services to propagate or penetrate other computers. A copy of a virus will reach remote computers only if the infected object is, for some reason unrelated to the virus function, activated on another computer. For example: when infecting accessible disks, a virus penetrates a file located on a network resource a virus copies itself to a removable storage device or infects a file on a removable device a user sends an email with an infected attachment.

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

Once launched, the virus writes its code to the "explorer.exe" address space. The infected process then searches for all files with an .exe extension and appends the virus code to all files found.

Folders with the names listed below will not be scanned for files:

QQ
Windows
WINNT
Local SettingsTemp

The files listed below will not be infected:

wooolcfg.exe
woool.exe
ztconfig.exe
patchupdate.exe
trojankiller.exe
xy2player.exe
flyff.exe
xy2.exe
au_unins_web.exe
cabal.exe
cabalmain9x.exe
cabalmain.exe
meteor.exe
patcher.exe
mjonline.exe
config.exe

zfs.exe
neuz.exe
maplestory.exe
nsstarter.exe
nmcosrv.exe
ca.exe
nmservice.exe
kartrider.exe
audition.exe
zhengtu.exe

The virus is also able to download other malicious programs to the victim machine; these are programs which are designed to steal online game passwords. In order to do this, the virus sends a request which contains the victim machine's parameters to the following links (at the time of writing, these links were not active):
