Facebook founder Mark Zuckerberg has had his social media accounts hacked by a Saudi-based group that discovered his password was 'dadada'.
A group known as OurMine claimed responsibility for hacking Pinterest and Twitter accounts belonging to the billionaire, who recently became a father.
In a message posted on Twitter through Zuckerberg's own account, the group claimed it had found his password in a leaked LinkedIn password dump.
Twitter user @Ben_Hall posted a screen grab of the Facebook founder's Twitter and Pinterest account, giving his password 'dadada' and the hackers' calling card.
Mr Hall wrote: 'Ouch. Mark Zuckerberg's social media accounts have been hacked.'
According to Sky News, the group claimed it had accessed the accounts to 'test security', with a tweet, now deleted, reading: 'Hey we got access to your Twitter & Instagram & Pinterest, we are just testing your security, please direct message us.'
The Twitter account @finkd, which was created in February 2009, has more than 414,000 followers, but only has 19 tweets associated with it.
While the Pinterest account @Zuck has more than 13,000 followers and 700,000 five star reviews associated with it.
OurMine, whose own Twitter account has been suspended, have claimed responsibility for a number of high-profile hacks on YouTube, including Markiplier.
OurMine used the compromised accounts to post messages alerting Zuckerberg to the hack. On Twitter (pictured left), the group confirmed it obtained the password through the recent Linked in password dump, with Zuckerberg's Pinterest account @Zuck proclaiming 'Hacked By OurMine Team' (pictured right)
