The account of Twitter Inc Chief Executive Jack Dorsey was hacked on Friday afternoon, sending public tweets and retweets including racial slurs and curse words to 4 million followers before Twitter secured the account.
Twitter in a tweet said it was aware the account was compromised and investigating what had happened.
One of the tweets claimed Nazi leader Adolf Hitler was innocent, while others contained racist comments against black people and Jews.
There was also a tweet suggesting there was a bomb at Twitter’s headquarters: “Intel is there’s a bomb at Twitter HQ.”
The account also posted a hashtag that was used during the apparent hacks of several YouTube stars last week. It also shared a link to a server on gaming chat application Discord, though the server invitation link is no longer valid.
Shortly after the hack, the offensive tweets and retweets were deleted. Certain Twitter accounts named in the compromised tweets and retweets appeared suspended on Friday.

.@Jack’s account has been hacked.
The Tweets are coming from a source called Cloudhopper. Cloudhopper was the name of the company Twitter acquired a long time ago to help bolster their SMS service.
Looks like the hackers are Tweeting via the old SMS service…

The account also shared a link to a server on gaming chat application Discord, though the server invitation link is no longer valid.
“Encouraging any kind of hacking is in direct violation of our Terms of Service,” a Discord spokeswoman said in a statement to Reuters. “We are aware of this incident and both the server and the server owner were permanently removed from Discord within minutes of this being reported to us. We will continue to monitor and investigate this incident.”
Twitter later tweeted that Dorsey’s account is now secure and said there is no indication that its systems had been compromised.
Screenshots of the tweets appeared to show they were sent through Cloudhopper, a mobile text messaging service that Twitter acquired in 2010. Twitter did not immediately respond when asked to confirm if the hack took place via Cloudhopper.
Twitter shares were down less than 1% in after-hours trade following the hack.
