Discovered: March 2, 2006

Aliases: W32/Bagle-DO (Sophos), W32/Bagle.dy@MM (McAfee), Email-Worm.Win32.Bagle.fr (Kaspersky), W32.Beagle.DX@mm (Symantec), WORM_BAGLE.DQ (Trend Micro), Win32/Bagle.AN (CA), Win32.Bagle.FM@mm (BitDefender), Worm/Bagle.FS (Avira)

The email sent by this variant of the Bagle worm spoofs (impersonates) the From sender. The subject line will be one of the following:

Pay your debts before we come to you
Call to your lawer immidiately
Lawsuit against you
We wait your response

Three messages may be sent by the worm, all of a legal nature and all beginning with:

LAWSUIT AGAINST YOU (CLICK TO ATTACHED DOCUMENT FOR MORE INFORMATION)

The rest of the email plagiarizes example letters from various legal resources.

For example, one "Lawsuit Against You" email complains of receiving an unsolicited fax.

A second "Lawsuit Against You" email revolves around an identity theft / credit dispute. That letter was taken verbatim from a sample letter found on the Credit InfoCenter website.

The third "Lawsuit Against You" email revolves around a faulty auto repair claim aimed at Tucker's Fix-It-Quick Garage, and is taken from the Nolo legal resource website.

The email carries one of the following named attachments:

lawsuit.exe
explanation.exe
documents.exe

This Bagle variant installs itself to the Windows System directory as win32lib.exe and modifies the HKCU\..Run key to load this file whenever Windows is started.
