Last Friday, Twitter CEO Jack Dorsey’s twitter account got hacked by a group called the Chuckle Squad. The hackers tweeted racial slurs, anti-semitic messages and at least one Holocaust denial from Dorsey’s account. Some of these offensive tweets were up for about 10 minutes. However, all of these tweets were removed shortly after the hack began.
Sometimes after the attack, Twitter tweeted that “the account is now secure, and there is no indication that Twitter’s systems have been compromised.” Twitter later 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.” Twitter claimed the cell carrier apparently allowed the hackers to send the tweets using text messages.
The tweets appear to have come via Cloudhopper, a company that Twitter previously acquired to help with its SMS service. The hack appears to be from the same group that attacked a number of YouTubers last week, including beauty vlogger James Charles, Shane Dawson, and comedian King Bach. At the time, the people who’d been affected suggested their accounts were breached following a SIM card swap conducted by AT&T employees.
