The attacker used three of six Ethereum keys and three of five BNB Chain keys, all kept on the same device, to seize control of token bridges, deploy malicious code and drain or mint hundreds of millions of H tokens. The project has halted bridge deposits and withdrawals, is working with exchanges and law enforcement, and faces scrutiny as H trades well below its pre-breach level. Humanity Protocol explained how attackers were able to steal more than $36 million of its H token, and the cause was a serious lapse in how it secured its keys.
