Protos analyzes details of the Binance Ethereum chain hack: EIP-7702 was exploited to target specific addresses, with approximately $2.4 billion in stolen funds frozen. According to Protos, the attack partially leveraged the wallet delegation feature on Ethereum. Attackers deployed sweeping contracts, targeting the "Binance 14" address with 50 EIP-7702 authorizations and signing with its keys. Stolen funds from other addresses were transferred via regular transactions. Binance has removed the delegation for "Binance 14," and approximately $2.4 billion in funds removed from Binance's Ethereum wallets have been frozen or blacklisted.
