A fairly well-known hacker group, Ourmine, with 41,000 followers on Twitter, claimed on Sunday that they'd successfully hacked Mark Zuckerberg's Instagram, LinkedIn, Pinterest and Twitter accounts. 


On checking things out, Zuckerberg's verified Twitter account had been defaced

Ourmine went on to brag about their achievement in a tweet and asked Zuckerberg to contact the group.



Another message of a similar vein was left on a Pinterest account allegedly associated with Zuckerberg.

This may have been linked to a large-scale data dump that occurred on May 18 2012 because of LinkedIn who claimed that more than 100 million members' email and password combinations hacked.

During this breach, hackers apparently stole and publicly released a separate set of 6.5 million encrypted passwords that year.
