Microsoft Security Bulletin Scam
Date:08.28.2006
Threat Type: Malicious Web Site / Malicious Code
Websense® Security Labs™ has received reports of a new wave of email scams disguised as Microsoft Security Bulletins. Users receive an email message which urges the immediate installation of a cumulative security patch for the "plug and play" vulnerability. Although the Microsoft patch number is similar to a previous alert we issued in June (http://www.websense.com/securitylabs/alerts/alert.php?AlertID=228), the website and the code that gets downloaded and installed are different.
Upon visiting the site and running the code the user is infected with a password stealing Trojan Horse.

This update resolves a newly-discovered, privately-reported vulnerability.

An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
