Facebook’s social media accounts were temporarily taken over by a group of hackers on Friday 7th February during midday.

The group of hackers with the insignia  OurMine posted on Twitter and Instagram accounts for Facebook and Messenger, writing “even Facebook is hackable”.

OurMine claims its attacks are an attempt to show cyber vulnerabilities. In January it hijacked over a dozen accounts for teams in the US National Football League.

The group posted a statement on Facebook’s official Twitter handle.

 “Hi, we are OurMine. Well, even Facebook is hackable but at least their security is better than Twitter.”

It also hijacked the Facebook and Messenger accounts on Instagram to post a photo of OurMine’s logo.

Facebook’s website was not hacked.

Twitter confirmed that the hacking occurred via a third-party and that accounts were locked once it was alerted to the issue.

“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,” Twitter said in a statement.

OurMine is a Dubai-based hacking group that attacked the accounts of corporations and high-profile individuals in the past. In the past, it has temporality infiltrated the social media account of Twitter’s founder Jack Dorsey, Google’s chief executive Sundar Pichai, and the corporate accounts of Netflix and ESPN

The group claims its attacks are designed to show a lack of security. But it also instructs victims to use its services to improve safeguards.
