On Friday, Facebook revealed that it had suffered a security breach that impacted at least 50 million of its users, and possibly as many as 90 million.
What it failed to mention initially, and only revealed later, is that the flaw affects more than just Facebook. If your account was impacted it means that a hacker could have accessed any account that you log into using Facebook.
Facebook initially responded by logging out the 50 million people it knows were impacted by the attack, and another 40 million who had been looked up with the “View As” tool. It also put the “View As” feature on hold.
But the second revelation Friday indicates that the fallout may be far more widespread than initially indicated.
