Facebook Hack Compromises 50 Million Users

Facebook revealed today that it was the target of a data breach affecting up to 50 million users. The social media site discovered the hack earlier this week, took measures to contain it and alerted law enforcement authorities.

"On the afternoon of Tuesday, September 25, our engineering team discovered a security issue affecting almost 50 million accounts. We’re taking this incredibly seriously and wanted to let everyone know what’s happened and the immediate action we’ve taken to protect people’s security," read the social media site's statement.

90 million users logged out

The breach reportedly allowed attackers to take over control of users' accounts. Hackers are believed to have taken advantage of vulnerabilities in the code for Facebook's "View As" feature.

Facebook, therefore, automatically logged out almost 50 million potentially compromised accounts as an extra precautionary measure. The network also reset access tokens for another 40 million accounts that were subjected to a “View As” look-up in the last year.

In total, approximately 90 million people will need to log in again on the site or on any site-related apps. Affected users will receive a notification explaining the breach at the top of their News Feed.

The extra log in is a small price to pay to protect the security of people's private data. The social network said it will continue to investigate and update the public.
