Ethereum (ETH) creator Vitalik Buterin says that hackers used a SIM-swap scam to take over his account on the social media platform X to commit theft.
In a new post on the decentralized social network Farcaster, Buterin says that whoever committed the offense took over his T-Mobile phone number.
“Finally got back my T-Mobile account (yes, it was a SIM-swap, meaning that someone socially engineered T-Mobile itself to take over my phone number).”
SIM swapping happens when scammers contact a mobile phone carrier and trick them into activating the scam target’s phone number on a SIM card that they have. Once they have the SIM card activated they attempt to use it to intercept two-factor authentication codes (2FA) for the person’s accounts.
