Characteristics

Proactive detection: This worm is proactively detected by McAfee products as "virus or variant New Worm" (with the 4174 DATs or greater, with program heuristics and "scan compressed files" enabled.

The worm is written in Visual Basic and propagates via the following mechanisms:

  • Mailing itself to Outlook contacts list
  • Sharing itself over peer to peer file-sharing networks (eg. KaZaA, Morpheus etc)
  • Sharing itself over the local network

Additionally the worm also functions as a remote access trojan, enabling the hacker to connect to the victim machine.

The worm delivers a destructive payload: it terminates the process(es) of various security-related applications and deletes their associated files.

Mass-Mailing

The worm mails itself as ANAKON.JPG to the Outlook contacts list, using Outlook to construct outgoing messages. Outgoing messages are formatted as follows:

Subject:
  • Do you happy?
  • Riyadh Issue: Al-Qaeda vs FBI
  • Osama Bin Laden Come Back!
  • Al-Qaeda News: Bombing Mission Success!
  • Check This Out!
  • Re: can mali can!

P2P Propagation

The worm copies itself to the following directories in order to spread via P2P networks:

  • %ProgramFiles%\KMD\My Shared Folder\
  • %ProgramFiles%\Kazaa\My Shared Folder\
  • %ProgramFiles%\KaZaA Lite\My Shared Folder\
  • %ProgramFiles%\Morpheus\My Shared Folder\
  • %ProgramFiles%\Grokster\My Grokster\
  • %ProgramFiles%\BearShare\Shared\
  • %ProgramFiles%\Edonkey2000\Incoming\
  • %ProgramFiles%\limewire\Shared\

      (Where %ProgramFiles% is the system program files directory, eg. C:\PROGRAM FILES.)

      The following filenames are used to entice users to download/run the worm.

      • X-Men II Trailer.mpg.exe
      • The Matrix Reloaded.jpg.exe

      Remote Access Functionality

      The worm also contains backdoor functionality, although this was not exhibited in tested. Data within the worm suggests it enables the hacker to connect to the victim machine and issue various commands.

      Miscellaneous

      The worm also contains the following strings:

      Method of Infection

      This worm spreads via email, peer to peer file-sharing networks and by sharing itself from the victim machine.

      The worm installs onto the victim machine as:

      %SysDir%\ANACON.EXE

      (where %SysDir% is the Windows System directory, eg. C:\WINDOWS\SYSTEM)

      The following keys are set to hook system startup :

      HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run "AHU" = C:\WINDOWS\SYSTEM\ANACON.EXE

      HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices "Hvewsveqmg"= C:\WINDOWS\SYSTEM\ANACON.EXE

      HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run "Cvfjx" = C:\WINDOWS\SYSTEM\ANACON.EXE

      The following keys are added in order to share the local C:\:

      HKEY_LOCAL_MACHINE\System\ControlSet001\Services\lanmanserver\Shares "HACKERz"

      HKEY_LOCAL_MACHINE\System\ControlSet002\Services\lanmanserver\Shares "HACKERz"

      HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\lanmanserver\Shares "HACKERz"

      The following security-related applications are targetted. If found, processes are terminated and associated files are deleted (by creating a WININIT.INI on Windows 9x, with the relevant NUL=%filename% entries).

      Removal

      All Users:
      Use specified engine and DAT files for detection and removal.

      Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).

      Overview -

      This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.
