Technical Details

When the attached file is executed, the worm will mail itself to the each recipient in every address book. After mass mailing the following key is added to the registry:

HKEY_CURRENT_USER\software\Cindy\mailed
 

This variant also replicates using mIRC and Pirch IRC clients. It replaces the "script.ini" from mIRC and "events.ini" from Pirch installation directories, causing that the worm will send itself to the IRC user that joins the channel where an infected user is.

VBSWG.V also goes trough all local and network drivers from the system, and replaces every file with either ".vbs" or ".vbe" extension with itself. It also attempts to locate mIRC and Pirch installations from these drives.

This variant shows the following message box upon execution:

Error Decompressing JPEG Picture
