BlockBeats 消息，8 月 24 日，慢雾创始人余弦转发 ScamSniffer 发布的安全预警表示，今日再度有用户因签署 EIP-7702 网络钓鱼批量交易而损失了约 154 万美元，涉及 ETH、BTC 等多个在以太坊上质押的代币。原理是 EIP-7702 利用，将用户 EOA 地址委托授权给 MetaMask: EIP-7702 Delegator，并通过其合约调用完成后续 Token 转移操作。该钓鱼手段已被主流钓鱼团伙工程化实践，若不慎被诱导交易将损失整个账户资产。提醒用户确认交易前确认网站与链接真实性，防止欺诈。
此前 8 月 22 日，据 ScamSniffer 监测，某用户签署了伪装成 Uniswap 掉期交易的钓鱼批量 EIP-7702 成交申请后，损失了约 100 万美元的代币和 NFT。攻击者通过伪装成 Uniswap 交易界面，诱导用户签署交易，并在交易中嵌入恶意代码或授权。
