PSA: Massive Facebook Breach Stole Login Info of 50 Million Accounts

Third-party apps like video games could also be at risk.

In a call with journalists today Facebook CEO Mark Zuckerberg confirmed that there was a breach to the popular social media site that resulted in over 50 million Facebook account login details stolen by an unknown hacker or hacking group. This breach particularly dangerous because it affects third-party apps that users might have used their Facebook accounts to log into, including third-party games.

"On Tuesday, we discovered that an attacker exploited a technical vulnerability to steal access tokens that would allow them to log into about 50 million people's accounts on Facebook," Zuckerberg wrote in a post on his Facebook page. "We do not yet know whether these accounts were misused but we are continuing to look into this and will update when we learn more."

According to The Verge the flaw was multi-layered starting with a vulnerability in the "View As" feature that lets users view what their Facebook page looks like as other users. The feature apparently exposed the security tokens that the hacker could then use to gain access to a person's account, and third-party apps that use Facebook logins.

Facebook says that it has fixed the issue and affected accounts have been forcibly logged out of their Facebook accounts. So, if you have to re-log into Facebook for some unknown reason today it could be a result of the breach, and you should probably review your passwords.

We're alerting our readers because many third-party apps which use your Facebook logins are video games, or video game accounts. Please review your security info and make sure nothing looks out of the ordinary if you used your Facebook account to log into a video game, or video game user account.
