Gibbs Mura, a U.S. law firm, has initiated a class action investigation into the recent hack of Drift Protocol, which resulted in the theft of approximately $280 million to $285 million in assets. The investigation focuses on potential claims by investors against Circle Internet Financial, following the attack on April 1, 2026. The hacker transferred over $230 million in USDC to Ethereum using Circle's Cross-Chain Transfer Protocol, with Circle opting not to freeze the funds. The breach, suspected by Elliptic to be linked to a North Korean state-sponsored group, led to a significant drop in Drift Protocol's total value locked (TVL) from $550 million to under $250 million. Additionally, the DRIFT token price fell by over 40%, and at least 20 DeFi protocols experienced indirect losses. Notably, Circle had previously frozen 16 commercial wallets in a separate civil dispute just days before the hack.
