INTERNET (SEPTEMBER 28, 2018) (SOCIAL MEDIA SITES) – Facebook Inc has discovered a security flaw affecting about 50 million user accounts which could have allowed attackers to take over those accounts, the social networking company said on Friday (September 28.
Attackers stole Facebook access tokens through its “view as” feature, which they could then use to take over people’s accounts. “View as” allows users to see what their own profile looks like to someone else.
Facebook has reset the access tokens of the 50 million affected accounts, and as a precaution, reset access tokens for another 40 million that have been looked up through the “view as” option over the last year.
The company would need to continue developing new tools to make its accounts more secure and prevent similar incidents, he added.
In 2013, Facebook disclosed a software flaw that exposed 6 million users’ phone numbers and email addresses to unauthorized viewers for a year, while a technical glitch in 2008 revealed confidential birth-dates on 80 million Facebook users’ profiles.
