Facebook’s accounts on Twitter and Instagram were hacked

Hackers temporarily took over Facebook’s accounts on Twitter and Instagram on Friday through a third-party platform, raising concerns about the security of the social networks. Both accounts are back to normal.

Hacker group OurMine temporarily took over Facebook’s Twitter account on Friday.

At around 3:50 p.m., hacker group OurMine tweeted from Facebook’s Twitter account. The same group also hijacked the Twitter accounts of more than a dozen NFL teams in January before the SuperBowl and has also hacked the accounts of tech moguls such as Facebook CEO Mark Zuckerberg, Twitter CEO Jack Dorsey and Google CEO Sundar Pichai.

“Well, even Facebook is hackable but at least their security better than Twitter,” the group said in a tweet that has now been deleted. Hackers also compromised the Twitter account for Facebook’s messaging service.

Around the same time, the group took over Facebook’s Instagram account and posted photos of the group’s logo.

A Twitter spokeswoman confirmed that Facebook’s account was hacked through a third-party platform. “As soon as we were made aware of the issue, we locked the compromised accounts and are working closely with our partners at Facebook to restore them,” she said in a statement. Twitter declined to name the third-party platform, but a screenshot of the tweets show that the posts came from social media management tool Khoros. Instagram and Khoros didn’t immediately respond to a request for comment.
