Yearn Finance's yETH product was attacked, and the attacker appeared to exploit a vulnerability to mint nearly unlimited yETH, thereby draining the pool in a single transaction and profiting approximately 1,000 ETH (approximately $3.00M), some of which has been transferred to Tornado Cash; on-chain data shows that the attack involved multiple newly deployed and subsequently self-destructed contracts, and the specific scale of losses has not yet been clarified.

Yearn stated that it is investigating the yETH LST stable pool-related incident, emphasizing that V2 and V3 Vaults were not affected.
