The Facebook originator’s account on sites including Instagram, Twitter, LinkedIn and Pinterest seem to have been briefly hacked on Sunday.
The responsibility was claimed by the hacker team called Ourmine, which has Twitter followers in thousands.
The so-called boastful statement of the hacker’s team in a tweet saying that had welcomed Mr Zuckerberg to contact them.
Tech news magazine Engadget took a screengrab of the Tweet in which OurMine said:
“Hey @finkd (Mark Zuckerberg’s Twitter handle) we got access to your Twitter & Instagram & Pinterest, we are just testing your security, please dm (direct message) us.”
The Twitter account has since had the offending tweets deleted.Mr Zuckerberg has not been tweeting from the account since 2012.
Developer Ben Hall tweeted a screenshot of Mr Zuckerberg’s “hacked” Pinterest page:
Some reports suggested that the 2012 hack of LinkedIn may have been responsible for the breach.
It was reported a month ago that 117 million LinkedIn username and password combinations stolen four years ago and were sold on dark web for 5 bitcoins – worth about $2,300 (£1,595).
The passwords were encoded, however it seems to have been generally simple to find.It has not been verified whether Mr Zuckerberg’s account on Instagram was hacked or not.
The account, on which he has posted only 30 pictures, has more than 600,000 followers.
