The official Twitter and messenger accounts of Facebook were hacked by a group that offered their services to the tech giant so they can improve their security.

A spokesperson of Facebook confirmed that they were hacked by a group through a third-party platform on Friday.

OurMine, the hacker group, hacked the Twitter account of Facebook at around 3:30 pm on Friday and said: “even Facebook is hackable but at least their security better than Twitter.”

The group also promoted their services by writing, “To improve your accounts security, contact us.”

They then took over the Instagram account of Facebook and started to post images of their logo on their page.

The posts were soon taken down by the tech giant.

The Twitter spokesperson of Facebook said, “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.”

This is not the first time the group hacked someone’s account.

In January this year, a number of NFL teams had their Twitter accounts hacked by the same group before SuperBowl began.

The account of Jack Dorsey, the Chief Executive of Twitter, was hacked in August last year.

The hack allowed an unauthorized person to send public tweets, which included racial slurs and curse words to the 4 million followers of Dorsey.

Earlier, Facebook admitted that a huge security breach happened, which saw nearly 50 million users have their accounts taken down by hackers.

Mark Zuckerberg, the founder of Facebook, said, “I’m glad we found this and fixed the vulnerability. But it definitely is an issue that this happened in the first place. I think this underscores the attacks that our community and our services face.”
