Vitalik confirms that X account was previously subjected to a SIM card swap attack.

BlockBeats reported on September 12th that Vitalik announced on social media that he had recovered his T-mobile account and confirmed that the previous attack was a SIM card exchange attack. Vitalik explained that, in terms of X, holding a phone number is enough to reset the account password. He had previously seen the advice that "phone numbers are not secure, do not use them for identity verification," but did not realize the problem. It is currently speculated that the phone number was leaked when registering for Twitter Blue. As previously reported by BlockBeats, Ethereum co-founder Vitalik's Twitter account was hacked on September 10th and phishing links were posted. According to ZachXBT, the hacker stole about $691,000 in total.
