According to @PeckShieldAlert, Yearn Finance suffered an approximately $9 million exploit where an attacker minted a near-infinite amount of yETH and drained the pool in a single transaction, and about 1,000 ETH (around $3 million) was sent to Tornado Cash (source: @PeckShieldAlert on X, Dec 1, 2025). For trading, monitor YFI spot and perpetual markets, yETH-linked liquidity, and on-chain flows related to the 1,000 ETH mixer outflow flagged in the report for signs of liquidity stress or volatility (source: @PeckShieldAlert on X, Dec 1, 2025). Consider tightening risk on DeFi exposure and setting alerts for additional transfers from the exploiter wallet given the confirmed pool depletion and Tornado Cash routing described in the alert (source: @PeckShieldAlert on X, Dec 1, 2025).
