Enso reveals malicious liquidity pool attack, resulting in Curve pool causing inflated quotes of $225000

DeFi infrastructure company Enso has revealed a malicious liquidity pool attack that returns false quotes by manipulating trading simulations. A manipulated Curve pool processed over 129000 exchanges, resulting in approximately $225000 in inflated quotes, and over 37000 transactions rolled back, consuming nearly $30000 in gas fees. On Polygon, a malicious Uniswap v4 hook triggered a 99.1% transaction failure rate. Enso has updated its execution protection product Enso Shield to detect false quotes in Ethereum and Polygon environments.
