It’s emerged that hackers from China launched a major attack on the UK Parliament earlier this month, exploiting the Windows Meta File (WMF) vulnerability which was so widely publicized during that time. The PCs of more than 70 individuals were compromised, including those belonging to researchers, secretaries and MPs.

Emails were sent to staff, with an attachment that contained the WMF-exploiting Setabortproc Trojan. Anyone opening this attachment would have enabled attackers to browse files, and possibly install a keylogging program to attempt the theft of passwords. None of the emails got through to the intended targets, MessageLabs said, but the UK authorities were alerted.
