Facebook spokesman Andrew Noyes, said "recently, we experienced a coordinated spam attack that exploited a browser vulnerability," "Our efforts have drastically limited the damage caused by this attack, and we are now in the process of investigating to identify those responsible."
Noyes says users were "tricked into pasting and executing malicious javascript in their browser URL bar causing them to unknowingly share this offensive content."

He says Facebook has "put in place new measures to reduce these attacks and will continue to iterate on our defenses to find new ways to protect people." Some users expressed their annoyance via Twitter, with a few indicating they were deactivating their accounts, says Sophos senior security analyst Graham Cluley. Speculation that the hackers associated with the renowned hacktivist group, Anonymous, were behind the attack circulated on gossip site Gawker.
