Twitter co-founder Jack Dorsey’s account has been compromised.
A hacking group called ‘Chuckling Squad’ have sent racist messages and bomb threats from his social media account.
Twitter spokesman Brandon Borrman confirmed the attack, saying: ‘Yes, Jack’s account was compromised.
‘We’re working on it and investigating what happened.’
Hackers, who posted the N-word on Jack’s account, used mobile messaging app Cloudhopper to send the tweets, according to Variety.
Twitter purchased Cloudhopper nine years ago.
