The Arbitrum Security Council took emergency action on the evening of April 20, Eastern Time. With the assistance of law enforcement agencies, it successfully froze and transferred 30,766 ETH related to the KelpDAO vulnerability. These funds have been moved to an intermediate frozen wallet, and their subsequent disposal will be coordinated and decided by the Arbitrum governance mechanism. The Security Council stated that this operation did not affect other on-chain states or users.
On-chain monitoring shows that after approximately 30,000 ETH were frozen, the North Korean hacker group TraderTraitor has begun laundering the remaining funds. The attacker split the funds into multiple wallets and primarily bridged them to the Bitcoin network via THORChain, causing the protocol's daily transaction volume to surge to $211 million. The laundering process has utilized over 400 addresses, with some funds also mixed with illicit proceeds from past hacking incidents.
