The exploit code of the serious vulnerability that was patched recently has been published according to Microsoft.

The vulnerability affects three operating systems which are Windows Server 2003, XP, and 2000.

A spokeswoman for the company declined to specify where the code was found according to the article at The New York Times.

Attacks are still limited and targeted, even with the release of this new exploit code. The malware situation remains the same, as we’ve not seen any self-replicating worms, but instead malware that would be classified as Trojans, specifically the malware we discussed when we released the security update on Thursday,” said Mike Reavey of Microsoft.
