Websense Security Labs™ ThreatSeeker™ Network has detected another fake Facebook sites campaign, just 4 days after Websense warned of the Mark Zuckerberg Facebook Page Showing Rogue Comments hack. A malicious executable file appears on fake Facebook sites titled "Facebook Profile Photos". Websense customers have been protected against this attack with ACE, our Advanced Classification Engine.
