Evgeny Gaevoy, founder of cryptomarket maker Wintermute, updated the details of the attack, saying that the attack was in relation to the wallet they used for DeFi proprietary trading operations. Wintermute did use Profanity and an internal tool to generate addresses with many zeros in front. They moved to a more secure key generation script after June. And then, due to an internal (human) error, a wrong function has been called and we blacklisted the router instead of the operator (contract that signs). In addition, Evgeny Gaevoy said that a 10% bounty would be paid to the hacker if he returned $160 million in stolen assets to the 0x4f3a120E72C76c22ae802D129F599BFDbc31cb81 wallet address.Source
