According to an initial Twitter statement allowed a "security oversight" of the vendor hackers. Twitter's communications group later clarified that "the phone number associated with the account was compromised due to a security oversight by the mobile provider ."

The hacking appears to be from the same group that attacked a number of accounts belonging to YouTube celebrities last week on Twitter, including beauty vlogger James Charles, Shane Dawson and King Bach.

Daniel "Keemstar" Keem, who has communicated with the hackers on several occasions, suggested in a tweet that the telephone service provider was blamed, stating that the company inadvertently allowed hackers to call in and ask for a SIM card change on behalf of high-profile accounts.

The tactic matches Twitter's explanation of the Dorsey hack, which the company said was caused by hackers who used a phone number to send tweets through text messages.

Such a tactic is often known as "SIM hacking." It occurs when a hacker deceives a mobile operator to transfer the victim's mobile number to a new phone – one owned by the hackers. Hackers can then use Twitter & # 39; s "text-to-tweet" service to post tweets to the victim's account.

Wired reported that smartphone users can protect themselves from switching SIMs by adding a passcode to their transport account or using a third-party app – such as Google Authenticator and Authy – for two-factor authentication.
