Here's a tidbit
Kaspersky Labs, a leading information security software developer has detected a mass mailing of a new Trojan named Agent. Agent infects victim machines when users view graphics in BMP format.
Agent exploits a vulnerability in MS Internet Explorer versions 5.0 and 5.5 which allows malicious code to be launched on victim machines via modified BMP files. This vulnerability is a direct result of the Windows source code leak and was first detected on February 16, 2004.
Probably old news for some but I thought it may interest others here.
