On September 15, the Blockaid vulnerability detection system disclosed that a Safe wallet belonging to an unidentified user on Ethereum was attacked, resulting in a loss of approximately $7.73 million in rsETH. The attacker utilized a public keeper multi-call to direct a custom Uni V4 LP Safe module to a Hook-enabled liquidity pool they created. The relevant Hook unwrapped aEthrsETH into rsETH, and the proceeds from the attack were extracted via MEV within the blockchain.
