Yearn yETH was attacked, approximately 3 million USD worth of ETH flowed into Tornado Cash.

PANews, December 1, news reported by The Block, Yearn Finance's aggregated staking token product yETH was attacked. The attacker exploited a vulnerability to mint yETH almost infinitely, draining the pool's assets in a single transaction. On-chain data shows that the attacker subsequently transferred about 1,000 ETH (approximately $3 million) into the mixing protocol Tornado Cash. Multiple contracts used for the attack self-destructed after the transaction. The exact scale of the losses is still unclear, and Yearn stated that it is investigating the incident, noting that its V2 and V3 Vaults were not affected.
