Facebook reveals 50 million accounts breached in cyberattack

Facebook just announced that 50 million accounts were affected in a cyberattack that comprised users’ login information. According to a statement from the social media giant, hackers exploited a vulnerability in Facebook’s code that allowed them to steal access tokens – the things that let users stay logged on indefinitely – via the “View As” feature, which allows users to see what their profile looks like to others.
