Arrival Details

This Trojan may arrive bundled with malware packages as a malware component.

It may be hosted on a website and run when a user accesses the said website.

NOTES:

It is a component of a malicious Java archive file (.JAR) that is hosted in a malicious Web site.

Depending on the current user's permission set, this Java Class attempts to download and execute possibly malicious files from a certain Web site.

The download link depends on where the malicious Java Class is hosted. The downloaded file is saved as %User Temp%\{random file name}.exe.

(Note: %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000, XP, and Server 2003.)
