Twitter chief executive Jack Dorsey’s account was hacked on Friday, and used to post a series of erratic and offensive messages.
The tweets containing racial slurs and suggestions about a bomb showed up around 2000 GMT on the @jack account of the founder of the short messaging service.
Twitter later confirmed that the account was “compromised”.
“We’re aware that @jack was compromised and investigating what happened,” a Twitter spokesperson said.
Some of the tweets contained the hashtag #ChucklingSquad which was believed to indicate the identity of the hacker group.
The news comes with Dorsey and Twitter moving aggressively to clean up offensive and inappropriate content as part of a focus on “safety.”
