Twitter CEO Jack Dorsey’s Twitter account was hacked on Friday afternoon by a group that calls itself the Chuckle Squad.
On Friday afternoon, it was noted that several racial slurs, antisemitic messages and at least one Holocaust denial were tweeted from Dorsey’s account; And The tweets appear to have come via Cloudhopper, that was when twitter was alerted of the hack on the CEO's account.
Cloudhopper is a company that Twitter previously acquired to help with its SMS service. If you text 404-04 from the phone number linked to your Twitter account, that text will post to Twitter. The source in the tweet will be given as “Cloudhopper.”
Twitter pointed the blame at Dorsey’s cell carrier, saying that “the phone number associated with the account was compromised due to security oversight by the mobile provider,” which apparently allowed the hackers to send the tweets using text messages.
Twitter has, however, acertained that Jack's account is now secured “the account is now secure, and there is no indication that Twitter’s systems have been compromised.”
Although, Dorsey’s account has been hacked before. In 2016, the security firm OurMine hacked @Jack to send out a message about “testing your security.” The tweet also had a video and a link to OurMine’s website. (OurMine also hacked other CEOs, such as Facebook’s Mark Zuckerberg and Google’s Sundar Pichai.)
