Facebook CEO Mark Zuckerberg has had his Facebook account hacked - and he's happy about it.
Khalil Shreateh, a computer programmer from the West Bank, found a way to bypass security settings and post a message on any user's Facebook Wall.
And after getting no response by posting the hack on the official "white hat" page, he simply posted a message on the wall of Facebook CEO Mark Zuckerberg instead.
He should have been eligible for a $500 bounty for finding bugs on the site. But according to reports he may have put that in jeopardy by breaking the site's rules. Either way, he's down the site a service. The flaw has now been fixed.
