Facebook briefly blocked breaking news stories about its security breach — and that’s a problem

This afternoon, Facebook held an emergency press conference to disclose a startling security breach. The company said 50 million Facebook accounts were affected in a hack that allowed attackers to control an account as if they were the account holders.

"Since we’ve only just started our investigation, we have yet to determine whether these accounts were misused or any information accessed," said Facebook’s VP of product management Guy Rosen during a morning press call. "We also don’t know who’s behind these attacks or where they’re based."
