Arbitrum Security Council Freezes $71 Million in Ether Linked to Kelp DAO Exploit

A significant portion of the funds stolen from Kelp DAO is now frozen. On Monday, Arbitrum's Security Council took action to secure 30,766 ETH, valued at approximately $71 million, which was linked to the $292 million rsETH exploit that occurred on Saturday. This action was taken in collaboration with law enforcement, who provided insight into the exploiter's identity. The frozen funds, which represent about a quarter of the total amount stolen, have been moved to an intermediary wallet that can only be accessed through further governance action. The exploit, which was attributed to North Korea's Lazarus Group by LayerZero, involved the theft of 116,500 rsETH from Kelp's LayerZero-powered bridge. Arbitrum, a layer-2 blockchain built on top of Ethereum, has a Security Council with the power to intervene in emergency situations such as this. However, such interventions are rare and can be controversial due to the level of control they introduce into an otherwise permissionless network. The freeze provides Kelp with a potential recovery option, in addition to any other funds that law enforcement and chain-tracing firms may be able to recover. It also raises questions about the responsibility for the exploit and the potential for further action to be taken. Kelp is currently working with ecosystem partners to establish a recovery fund and is considering its next steps, while LayerZero has not publicly commented on the situation. The ability to freeze additional stolen funds will depend on the actions of the attacker and the responses of other chains involved.
