Reproducible Foundry test fork from SunWeb3Sec/DeFiHackLabs. Clone the repo, run forge test against the file path above, and replay the exploit against a mainnet fork at the historical block. Use for reproduction only — not for live targets.
An attacker exploited a vulnerability in the staking contract for Meta Pool, which is a liquid staking project. This allowed them to mint 9,700 mpETH, the project's liquid staking token, which is notionally worth $27 million. However, very low liquidity for the token meant that the attacker was only able to swap 10 ETH (~$25,000) of tokens. Attack method (per SlowMist): Contract Vulnerability. Reported loss: $ 25,000.
