FACEBOOK SAYS THAT up to 50 million accounts were breached in a security flaw exploited by hackers.
The giant social network said it learned this week of the attack that allowed hackers to steal “access tokens”, the equivalent of digital keys that enable them to access their accounts.
“It’s clear that attackers exploited a vulnerability in Facebook’s code,” vice president of product management Guy Rosen said in a blog post.
We’ve fixed the vulnerability and informed law enforcement. Facebook chief executive Mark Zuckerberg said engineers discovered the breach on Tuesday, and patched it last night.
“We don’t know if any accounts were actually misused,” Zuckerberg said.
