Binance Co-CEO: Attackers Used Self-Destruct Mechanism, Making Tracking and Investigation More Difficult Binance Co-CEO Richard Teng (@_RichardTeng) announced updates on the investigation into the approximately $6.3 billion hack on October 30th, stating that it was not a solo operation. Initial investigations pointed to a compromised laptop, but the team subsequently discovered other entry points. The attackers also used a self-destruct mechanism to erase tools and traces during the operation, increasing the difficulty of tracing. He stated that the attackers gained on-chain execution privileges on hot wallets through EIP-7702, and the related delegation did not go through Binance's normal approval process. Binance has therefore suspended withdrawals and is rebuilding and testing the relevant systems, aiming to restore service within approximately 40 hours, while cooperating with law enforcement and other agencies to track the stolen funds.
