Slow Mist Cosine stated that the core reason is that Safe multi signature was breached, similar to the previous Radiant Capital case, which may have also been stolen by North Korean hackers. Bybit has officially announced the detection of unauthorized activity involving one of our ETH cold wallets. At the time of the incident, our ETH multi signature cold wallet executed a transfer to our hot wallet. Unfortunately, this transaction was manipulated through a complex attack that obscured the signature interface, displayed the correct address, and altered the underlying smart contract logic. Therefore, attackers can take control of the affected ETH cold wallet and transfer its assets to an unrecognized address. We want to assure our users and partners that all other Bybit cold wallets are completely secure. All customer funds are safe, and our operations continue as usual without interruption. Our security team is actively investigating this incident in collaboration with leading blockchain forensics experts and partners. Any team with expertise in blockchain analysis and fund recovery that can assist in tracking these assets is welcome to collaborate with us.
