Wu Blockchain recaps Richard Teng's Oct 30 hack update: multiple attackers, extra entry points beyond the laptop, self-destruct mechanisms that erased tools and traces, and an EIP-7702 delegation that bypassed Binance's approval controls
Binance Co-CEO Richard Teng updated the investigation into the roughly $6.3 billion hack on October 30, saying multiple people were involved. Investigators initially suspected a compromised laptop but later found other entry points. Attackers used self-destruct mechanisms to erase tools and traces, complicating the investigation. Teng said they used EIP-7702 to gain on-chain execution authority over a hot wallet without passing Binance's normal approval controls. Binance paused withdrawals to rebuild and test its systems, targeting restoration within 40 hours.
