A group known as OurMine claimed responsibility for hacking Pinterest and Twitter accounts belonging to the billionaire, who recently became a father.
In a message posted on Twitter through Zuckerberg’s own account, the group claimed it had found his password in leaked LinkedIn in password dump.
According to Sky News, the group claimed it had accessed the accounts to ‘test security’, with a tweet, now deleted, reading: ‘Hey we got access to your Twitter & Instagram & Pinterest, we are just testing your security, please direct message us.’
