Characteristics

This threat is proactively detected as New MSVB P2P worm when using the 4266 DAT files with the 4.2.40 scan engine and scanning compressed executables (a default scan option).

This variant of the worm is very similar to previous variants. It is intended to propagate via email and sharing itself over P2P networks.

The worm consists of a 3-file sandwich:

DROPPER COMPONENT | PROPAGATION COMPONENT | SMTP LIBRARY

The dropper component is intended to drop and run the other components:

  • Propagation component: 56,614 bytes
  • SMTP library: 25,737 bytes

Strings within the dropper and propagation components suggest the worm is intended to arrive in a message with the following characteristics:

From: Dispatch@McAfee.com

Various subject lines and message bodies are carried within the worm:

'''*< Love Speaks it all >*'''

Co0o0o0o0oL

Running the attachment infects the local system. The worm extracts several files to the WINDOWS SYSTEM directory:
  • explore.exe (24,064 bytes)
  • SMTP.ocx (25,737 bytes)
A registry run key is created to load the worm at system startup:
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
    Run "Explore" = C:\WINDOWS\SYSTEM\EXPLORE.exe
It also copies itself to the WINDOWS SYSTEM directory using the aforementioned email attachment names. The worm attempts to configure KaZaa to use the WINDOWS SYSTEM directory as the default shared folder.

Symptoms

- Presence of the aforementioned filenames
- The virus creates a counter registry value:

  • HKEY_CURRENT_USER\DeathTime = %Run count%
If the run count exceeds 30, the worm attempts to delete all files on the local system, and displays several message boxes, one at a time. After OK has been clicked on the last box, the system is restarted.

Method of Infection

This worm spreads via email and the KaZaa P2P file-sharing network.

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).

Additional Windows ME/XP removal considerations

All Information

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.
