A sophisticated exploit targeting Yearn Finance’s yETH has led to a significant loss of funds. According to reports from Foresight News, the attacker exploited a vulnerability within the yETH protocol, allowing for unlimited minting. This resulted in a rapid draining of the entire yETH pool via a single transaction, with approximately 1,000 ETH, valued at $3 million, being transferred to Tornado Cash. The attack appears to have been conducted using multiple newly deployed contracts, some of which self-destructed immediately after transferring funds. The impact on the original $11 million fund size of yETH remains unclear as authorities continue their investigation. Yearn Finance officials have confirmed that their V2 and V3 vaults remain unaffected from this incident.
