Fake Microsoft alert comes with free Trojan

by Nikola Strahija on July 1st, 2005 The e-mail identifies itself as Microsoft Security Bulletin MS05-039, and offers a link to what it claims is a patch against the Sober Zafi and Mytob worms.

Bulletin MS05-039 doesn't exist and a phoney patch is a variant of the SDBot Trojan software, which is at present not detected by anti-virus software products, according to a report form security research firm WebSense.

The risk is low right now because the server, which hosts the Trojan, appears to be inactive. That server, hosted by, exceeded its allowed bandwidth and was shut down.
A fundamental mistake, but one that will most likely not be repeated in future.
