On December 1st (UTC+8), Yearn Finance's yETH product was suspected of being attacked today. The attacker exploited a vulnerability that allowed for "unlimited minting" of yETH, quickly draining the entire yETH pool in a single transaction.

According to on-chain data, approximately 1,000 ETH (approximately $3.00M) was subsequently transferred to Tornado Cash. The attack appears to have been carried out through multiple newly deployed contracts, some of which self-destructed immediately after the transaction. It is currently uncertain how much of the original $11.00M in the yETH pool was affected.

The incident was initially discovered by X user Togbe while monitoring large transfers. Yearn officials say they are investigating the matter and emphasize that their V2 and V3 Vaults were not affected. The entire event is still developing.
