Cyber attackers broke into the Facebook’s boss’s Twitter and Pinterest accounts and posted messages celebrating their success. They appear now to have been restored.
According to messages that the hackers posted on the accounts before they were deleted, they got in using passwords that had been exposed as part of a huge LinkedIn data dump. Those passwords were stolen in 2012 but were made public last week, when they were found to be sale online to anyone with the money to buy them.
The hackers got hold of that database of logins and presumably used that same password to get access to the Twitter account, if the tweets posted to Mr Zuckerberg’s account are to be believed.
“You were in Linkedin Database … DM for proof,” the hackers, identifying themselves as OurMine, posted on Mr Zuckerberg’s Twitter account. They also changed the name of his Pinterest account to “Hacked By OurMine Team”.
The hackers also claimed to have got into Mr Zuckerberg’s Instagram, but Facebook has denied that they got into that or any other system owned by the company.
