Binance investigates multibillion-dollar security breach

Binance is investigating a potential multibillion-dollar security breach involving one of its Ethereum wallets, after suspicious transfers prompted stablecoin issuers Tether and Circle to reportedly freeze billions in assets.

A Binance spokesperson told Cointelegraph on Thursday that the exchange was investigating reports of a potential security issue but had not confirmed any impact on user funds. The spokesperson said its security teams were reviewing the activity and would provide updates once more information was verified.

Concerns were first raised by blockchain researcher Spreek, who posted on X that assets from a Binance-linked Ethereum wallet had been transferred to a newly created address through a contract call allegedly funded by Tornado Cash. Spreek later reported that wallets connected to the transfers had begun selling Tether USDt (USDT) through decentralized exchanges.
