What I did:
When I was looking through BBC News, and came across an interesting article.
The Facebook founder's accounts on sites including Instagram, Twitter, LinkedIn and Pinterest appear to have been briefly compromised on Sunday.
A hacker group called Ourmine, which has more than 40,000 Twitter followers, claimed responsibility.
The group bragged about the alleged hasks in a tweet and invited Mr Zuckerberg to contact them.
"Hey @finkd we got access to your Twitter & Instagram & Pinterest, we are just testing your security, please dm us."
Some reports suggested that the 2012 hack of LinkedIn may have been responsible for the breach.
