According to Blockaid monitoring, an attack was discovered on an unidentified user's Safe multi-signature wallet on Ethereum. The attacker introduced a custom Uni V4 LP Safe module into a liquidity pool they created through a public keeper multicall, and then the hook unpacked aEthrsETH into rsETH, completing the extraction of Yoink MEV within the block. Currently, two transactions have been confirmed to cause approximately 7.73 million dollars in rsETH losses.
