Facebook says 50M user accounts affected by security breach
NEW YORK — Facebook says it recently discovered a security breach affecting nearly 50 million user accounts.
The hack is the latest setback for Facebook during a year of tumult for the global social media service.
In a blog post , the company says hackers exploited a bug that affected its “View As” feature, which lets people see what their profiles look like to someone else. That would let attackers steal the “access tokens” Facebook uses to keep people logged in. Possession of those tokens would allow attackers to “seize control” of user accounts, Facebook said.
Facebook says it has taken steps to fix the security problem and alerted law enforcement.
