Facebook announced earlier today that its social network had been hacked, resulting in 40 million accounts that were directly impacted. Attackers exploited a feature in Facebook called View As which essentially shows how your profile looks to others. The flaw enabled them to get ahold of so-called Access Tokens, which allowed them to be logged in as genuine Facebook users without having to use their password. A law enforcement investigation is ongoing to determine the full scope of this hack and identify the eventual perpetrators.”]
