Facebook founder Mark Zuckerberg's Twitter and Pinterest accounts were briefly hacked over the weekend by a group calling itself OurMine.

It appears the social media guru skipped the advice to get a secure password, as tech magazine Engadget captured a tweet from OurMine revealing his password was "dadada." Zuckerberg recently became a dad.

Facebook Inc. released a statement Monday saying no Facebook accounts had been compromised by the hack.

OurMine messaged Zuckerberg, who goes by the Twitter handle @finkd, to say it had found his password on a LinkedIn database of user details that was leaked widely last month.

That leak has given hackers access to a wealth of password details.

In tweets that have since been deleted, OurMine posted on Zuckerberg's Twitter page "Hey @finkd we got access to your Twitter & Instagram & Pinterest, we are just testing your security, please dm (direct message) us."

It hasn't been verified that the Instagram account, owned by Facebook, was indeed hacked.

Twitter has deleted OurMine's account, but under another address, @OurMineTeam43, the hacker group tweeted that it was trying to alert Zuckerberg to the security risk.

Zuckerberg has accounts with several rival social media companies, such as Twitter and LinkedIn, but none of them are very active.
