The tweets were visible for up to 20 minutes before the network solved the problem. The tweets included messages such as “Hitler is innocent.” The company suspended many accounts involved in the attack. It’s supposed that a group called Chuckle Squad was likely responsible. Even if Dorsey used two-factor authentication for his Twitter account, hackers have learned how to get around this extra security measure. “The phone number associated with the account was compromised due to a security oversight by the mobile provider. This allowed an unauthorized person to compose and send tweets via text message from the phone number. That issue is now resolved,” the company said in a tweet.
The attack may be a replica after Twitter and Dorsey have promised to improve the “health” and civility of discourse on the social media service, cracking down on hate speech and abuse. Also there was a precedent: in 2016, Dorsey’s account was taken over by the hacker group OurMine. Twitter said on Friday that it was investigating the hacking of Dorsey’s account, adding that there was “no indication that Twitter’s systems have been compromised.” However the fact is that someone was able to exploit its platform.The company has kept silent about the safeguards it has in place for Trump’s account.
