[SlowMist's Yu Xian: Binance Attackers' On-Chain Operations Weak and Were Pre-Practiculated; Use of EIP-7702 Was Only for Convenient Mass Swipes] Jinse Finance reported on October 30th that Yu Xian, founder of SlowMist, stated that the attackers chose EIP-7702 on Ethereum primarily to facilitate the mass swiping of tokens from Binance-related hot wallets. From an on-chain perspective, their operations were rather crude, and they rehearsed for several hours before the actual theft; the first five transactions of the relevant addresses can be referenced. Yu Xian pointed out that the EIP-7702 mechanism itself is not flawed; even without this protocol, there are other ways to achieve a similar effect.
