Incident Overview
The DeFi protocol Set Protocol (involving Index Coop’s ExchangeIssuance contract) was exploited due to insufficient state locking in the smart contract. The attacker used a malicious manager pre-issue hook to artificially inflate asset valuations (e.g., positionMultiplier), causing the contract to transfer excess assets based on falsified data, resulting in a loss of approximately $9,600.
