Law Firm Files Restraining Notice for Kelp Exploit ETH

Gerstein Harrow has filed similar cases in the past, arguing its clients have a claim to funds stolen by the DPRK and frozen by crypto firms.

A US law firm has filed a restraining notice to block the transfer of frozen Ether from the Kelp exploit, arguing that its clients are owed over $870 million in compensation and damages by North Korea.

Charlie Gerstein, a lawyer for US law firm Gerstein Harrow LLP, said in a post on the Arbitrum DAO forum on Friday that a New York district court signed off on a restraining notice and three writs of execution preventing the DAO from moving the Ether under threat of contempt of court.

The law firm argued that its clients, who were not affected by the Kelp exploit, won default judgments against North Korea in three separate US court cases in 2010, 2015 and 2016 and are owed a collective $877 million in compensatory and punitive damages, plus interest. It also argued its clients have a claim on DPRK property.

The freeze could mean those affected by the Kelp exploit would need to wait longer to see their funds recovered. This also isn’t the first time the firm has attempted to lay claim to stolen cryptocurrency.

Kelp DAO suffered a $292 million hack on April 18, which is believed to have been carried out by TraderTraitor, a subgroup of North Korea’s state-backed hacking unit, Lazarus Group.

Days later, Arbitrum’s security council took emergency action to freeze 30,766 Ether (ETH), worth over $73 million, held in a wallet linked to the Kelp exploit.

According to the restraining notice, Gerstein said the stolen Ether is “property” in which the DPRK has a stake because the hacker group is affiliated with the country.

Funds were proposed for Kelp victims

Aave Labs proposed on April 25 that the Arbitrum DAO unfreeze the $73 million in Ether tied to the Kelp DAO attack and direct those funds to “DeFi United,” a fund aimed at restoring rsETH and compensating its holders.

An Arbitrum DAO member under the handle Zeptimus said that if the law firm’s action is successful, the DPRK debt will be transferred to the Kelp DAO victims.

“Your clients’ losses are real and the DPRK should answer for them. But the remedy the restraining notice asks for, blocking the return of stolen funds to their actual owners shifts the cost of the DPRK’s debt onto a different set of victims who were themselves robbed. That compounds the original harm; it doesn’t redress it,” they said.

Gerstein Harrow filed similar claims before

Gerstein Harrow has filed similar cases in the past, arguing its clients have a claim to funds stolen by the DPRK and frozen by crypto firms. In February, the firm filed a claim against funds frozen by Tether that were stolen in the 2023 Heco Bridge hack.

It has also filed class action suits against multiple DAOs. At the same time, on-chain sleuth ZachXBT accused the law firm of using his research in court documents to stake a claim on funds from the $1.5 billion Bybit hack.

North Korea-affiliated bad actors have been accused of stealing at least $578 million across major incidents throughout April and have been linked to many of the industry’s largest hacks, including the Bybit exploit.
