Facebook finds 'no evidence' hackers accessed outside apps
October 02, 2018 / STEVEN MUSIL
Facebook says its investigation into a hack revealed last week has found "no evidence" that hackers accessed third-party apps. The breach, which Facebook said Friday had affected 50 million people on the social network, stemmed from a vulnerability in Facebook's "view as" feature, which lets people see what their profiles look like to other people. Attackers exploited code associated with the feature that allowed them to steal "access tokens" that could be used to take over people's accounts. Facebook revoked those tokens but also said the breach could affect third-party apps and services, such as Instagram, Tinder and Spotify. "We have now analyzed our logs for all third-party apps installed or logged during the attack we discovered last week," Guy Rosen, Facebook's vice president of product management, said in a blog post Tuesday.
