A hacking group has claimed responsibility for taking over social media accounts belonging to Facebook founder Mark Zuckerberg.
His Twitter and Pinterest pages appear to have been compromised for a short time on Sunday.
Some reports suggested that the 2012 hack of LinkedIn may have been responsible for the breach.
Last month it was reported that 117 million LinkedIn username and password combinations stolen four years ago were being sold on the dark web for 5 bitcoins – worth about $2,300 (£1,595).
The passwords were encoded, but in a form that appears to have been relatively easy to unravel.
The account, on which he has posted just 30 images, has more than 600,000 followers.[share title="Share this Post" facebook="true" twitter="true" google_plus="false" linkedin="true" pinterest="false" reddit="false" email="false"]
