New malicious email campaign targets Facebook users

A large wave of malicious emails claiming to come from Facebook began hitting inboxes this morning, according to researchers at messaging security firm AppRiver. The emails contain the subject line "Facebook Support" and purport to be from "Facebook office." Recipients are told their Facebook accounts have been blocked due to spam activity and they must use a new password, which is included in an attachment. However, the attachment actually contains a variant of the Oficla downloader, which has been known to install rogue anti-virus programs and the Zeus trojan. AppRiver has detected more than 100,000 of the messages. – DK
