[U.S. Law Firm Attempts to Block Kelp Attack Frozen ETH Transfer, Claims North Korea Owes $877 Million in Compensation] U.S. law firm Gerstein Harrow LLP has filed a restraining order with the New York District Court, seeking to prevent Arbitrum DAO from transferring 30,766 Ethereum (worth over $73 million) frozen due to the $292 million attack on the Kelp protocol. The firm stated that its clients obtained default judgments against North Korea in three cases from 2010, 2015, and 2016, demanding a total of $877 million in compensatory and punitive damages, and asserted that its clients have claims to North Korea-related assets. Kelp DAO was hacked on April 18, an incident believed to have been carried out by the TraderTraitor group under the Lazarus Group, a hacker organization reportedly backed by North Korea.
