The Twitter and Vine accounts belonging to Jack Dorsey, the CEO of Twitter, have been hacked.

Dorsey was hacked by OurMine security - a “three-man security team” which previously targeted the social media accounts of Google boss Sundar Pichai and Facebook CEO Mark Zuckerberg.

Now the group has aimed straight at Twitter’s core, releasing several Vine videos via Dorsey’s account which were also posted on his Twitter feed. The tweet read: “Hey, its OurMine,we are testing your security” and linked to their website. It has since been deleted.
