Facebook: Hackers didn't access third-party sites with our sign-in

The damage isn't quite as bad as some feared.

The Facebook hack compromised 50 million users, but the damage might not be as extensive as some expected. In a statement, company security VP Guy Rosen revealed that investigators "found no evidence" of the intruders accessing third-party apps with its Facebook Login feature. Some sites using the single sign-on also confirmed that there was no indication of a data breach on their end, although they're not necessarily taking chances.

Uber, for instance, had closed active sharing sessions from Facebook-based sign-ins while it looked into the case. TaskRabbit and travel site SkyScanner, meanwhile, were still determining the possible damage to their users.

The update isn't going to be very comforting if you're one of the 50 million affected users. However, it does indicate that the consequences of the hack won't permeate through the internet at large -- it's 'just' limited to Facebook. At this point, most of the concern revolves around the hackers' access to personal data, their origins and whether Facebook can limit the reach of future attacks.
