PANews reported on December 1st that, according to The Block, Yearn Finance's aggregated staking token product yETH was attacked. The attacker exploited a vulnerability to mint almost unlimited yETH, depleting the pool's assets in a single transaction. On-chain data shows that the attacker subsequently transferred approximately 1,000 ETH (about $3 million) to the mixing protocol Tornado Cash. Multiple contracts used for the attack self-destructed after the transaction. The exact scale of the losses is currently unknown. Yearn stated that it is investigating the incident and that its V2 and V3 Vaults were unaffected. Yearn also confirmed that its Katana Vaults are all V3 versions and were not affected by the yETH attack.PANews reported on December 1st that, according to The Block, Yearn Finance's aggregated staking token product yETH was attacked.
