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.

Upon execution, the worm copies itself to %SysDir% as:
(Where %SysDir% is the System directory, for example: C:\WINNT\SYSTEM32.)
The following Registry keys are added to hook system startup:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
Run "Config Loader" = SCVHOST.EXE
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunServices "Config Loader" = SCVHOST.EXE
As for the previous variant, this worm requires MSVCP60.DLL to run - this is a standard MS Visual C DLL, which if not present on the system, would prevent the worm from executing.
- Existence of the Registry keys and filenames detailed above
- Additional traffic on TCP ports 135 (MS03-026 related) and 445 (MS03-001 related).
- The worm references the NetScheduleJob API call and may create remote Scheduled Tasks on infected systems.
- Unexpected network traffic to following remote IRC server:
- Unexpected traffic to the following servers:
The worm attempts to terminate the following processes:
This worm propagates via accessible or poorly secured network shares, and is intended to take advantage of two high profile exploits:
When it attempts to spread through default administrative shares:
The worm contains a list of common user-names and passwords. This list contains typical poor username/password combinations. Users should avoid securing shares with passwords containing key sequences such as:
Once running on the victim machine the worm also acts as an IRC bot, and attempts to join a channel on the following remote IRC server:
Once connected, the bot can receive commands to perform various tasks, such as:
The worm also tries to steal game software CD keys:
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).
