According to PANews, the blockchain security platform Scam Sniffer has revealed that the phishing organization Inferno Drainer is leveraging Ethereum EIP-7702 to implement a new type of attack, resulting in a single loss of $150,000. EIP-7702 is a key part of the Pectra upgrade, allowing externally owned accounts to temporarily act as smart contract wallets during transactions. The attackers perform bulk token transfer operations through authorized MetaMask wallets. Yu Cosine, the founder of Slow Mist Technology, pointed out that the attackers use the 'execute' command to execute malicious bulk authorizations in the background. Security experts recommend that users regularly check their token authorization status and verify through Etherscan whether their wallets have been maliciously delegated.
