Binance hacker used the EIP-7702 mechanism to mass-drain tokens from hot wallets, rehearsing for hours before the theft

Odaily Report: According to monitoring by SlowMist's Cosine, the Binance hacker chose the EIP-7702 mechanism on Ethereum solely for convenience of sweeping — that is, to mass-drain tokens from Binance-related hot wallets. On-chain records show that the hacker's operations were rather crude, and they conducted several hours of rehearsal and preparation before the actual theft. The EIP-7702 mechanism itself is not the problem; even without this protocol mechanism, other methods exist.
