The two accounts posted identical messages at 7 p.m. Friday evening saying, "Hi, we are O u r M i n e. Well, even Facebook is hackable but at least their security better than Twitter."
A Twitter spokesperson confirmed Friday night that the two accounts were hacked "through a third-party platform."
At 8:49 p.m. Friday @Facebook tweeted that the company had secured and restored access to its Twitter account.
OurMine, the group that appears to have taken credit for the hack, is also believed to be behind the recent hack of several NFL teams' social media accounts as well as 2016 attacks on Variety magazine and Mark Zuckerberg's social media accounts.
The group positions itself as a security consultancy and claims the hacks are intended to draw attention to these accounts' security vulnerabilities.
