Even billionaire tech entrepreneurs get hacked.
Some of Facebook CEO Mark Zuckerberg's social-media accounts were hijacked late Sunday, with the attackers posting messages from them showing off their access.
The hacker(s) — who use the name OurMine Team — managed to get into Zuckerberg's Twitter and Pinterest accounts, and they also claimed to have broken into his Instagram account, though Facebook denied this to VentureBeat and there doesn't seem to be any evidence of it.
His password? "dadada."
(His Facebook account wasn't affected.)


The Facebook founder’s login details – and the password ‘dadada’ – were allegedly discovered in leaked LinkedIn data records
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.
A hacking group called Ourmine boasted about the alleged hacks, and asked the billionaire Facebook founder to contact them.
A message posted on his compromised Twitter account read: “Hey we got access to your Twitter & Instagram & Pinterest, we are just testing your security, please direct message us.”
Twitter reacted quickly to the hack, temporarily suspending his account before reinstating it with the tweet deleted.
The hackers claimed that they found his password – dadada – in the details of stolen LinkedIn accounts which were leaked online last month.
Almost 120 million LinkedIn username and passwords combinations were stolen four years ago, and recently appeared on the black market dark web.
It appears Mr Zuckerberg may have used the same password across multiple accounts.
Hackers had claimed that his Instagram account had been accessed, which would have been particularly embarrassing as the photo-sharing app is owned by Facebook.
But a spokesman for Facebook said: “No Facebook systems or accounts were accessed. The affected accounts have been re-secured.”
