Yearn: yETH pool suffers complex attack, with losses of approximately $8.9 million

Jinse Finance reported that Yearn issued a statement saying its yETH stable pool was attacked at 21:11 UTC on November 30. The attacker used a custom contract to mint a large amount of yETH, resulting in approximately $8 million in losses from the pool, with an additional loss of about $900,000 coming from the yETH-WETH pool on Curve. Yearn stated that the affected code is unrelated to other products, and both V2/V3 Vaults were not impacted. The complexity of the incident is similar to the previous attack on Balancer. The team is currently working with SEAL911 and the auditing firm Chain Security to investigate the matter.
