According to the source, a wallet reportedly lost 6.28M in stETH and aEthWBTC after signing multiple phishing permit signatures (source: user-provided alert). This report cannot be independently verified here because no wallet address or transaction hash was supplied (source: assessment of provided information). For trading impact, if confirmed, such drains can precede on-chain liquidations; monitor the stETH-ETH spread, Curve stETH/ETH pool imbalance, and WBTC liquidity for abnormal flows that may affect ETH, stETH, and WBTC pricing (source: observable DeFi market mechanics). Risk management actions include reviewing and revoking token approvals or permit allowances on relevant protocols and tracking potential mixer or bridge outflows that could signal imminent selling (source: standard on-chain security practice).
