Facebook says 50m user accounts affected by security breach


Facebook Inc says it has discovered a security issue affecting almost 50 million accounts. The social media company said engineers discovered the incident took place last Friday, on 25 September, and an investigation is still in the early stages.

Facebook said attackers stole Facebook access tokens through its “view as” feature, which they could then use to take over people’s accounts. “View as” is a feature that allows users to see what their own profile looks like to someone else. “Since we’ve only just started our investigation, we have yet to determine whether these accounts were misused or any information accessed,” the company said in a blogpost. Facebook shares fell 3% to $163.78 in afternoon trading.(theguardian)…[+]
