Inferno Drainer leverages Ethereum's EIP-7702 to carry out a new attack, resulting in a single loss of $150,000

PANews reported on May 26 that according to Beincrypto, the blockchain security platform Scam Sniffer disclosed that the well-known phishing organisation Inferno Drainer recently used Ethereum's EIP-7702 upgrade feature to carry out a new attack, which has caused a single loss of $150,000. EIP-7702 is a key part of the Pectra upgrade, which allows an externally owned account (EOA) to temporarily act as a smart contract wallet during a transaction, and attackers can perform bulk token transfer operations through an authorised MetaMask wallet.

Yu Sine, the founder of SlowMist Technology, pointed out that this attack marks an upgrade in phishing tactics: the attacker no longer directly hijacks the wallet, but uses the "execute" command to perform malicious batch authorisation in the background. Security experts recommend that users regularly check the token authorisation status and check whether the wallet has been maliciously delegated through tools such as Etherscan.
