Facebook CEO Mark Zuckerberg fell victim to hackers over the weekend after they got access to his Twitter,Pinterest and LinkedIn accounts.

OurMine,the group credited with the hacking,also targeted the billionaire’s Instagram account but is said that the site’s security systems prevented the account from being accessed.

A tweet from the group’s already suspended Twitter account read,

“Hey @finkd we got access to your Twitter & Instagram & Pinterest, we are just testing your security, please dm us.”

They went on to reveal Zuckerberg’s password which they found on a LinkedIn database of user details that was leaked online last month.

“You were in Linkedin Database with the password ‘dadada’!”

His Facebook account was however not among the compromised profiles.
