BlockSec Phalcon 更新 Aztec 漏洞事件分析,称根因并非缺少访问控制,而是 RollupProcessorV3 中 numRealTxs 未与 ZK 证明强制执行的交易集有效绑定。据 Foresight News 报道,证明验证路径会将 encodedInnerTxData 中所有交易解码并插入 rollup 默克尔树,但 L1 结算逻辑仅处理前 numRealTxs 个解码槽位。

攻击者利用该不一致,将真实存款交易放在靠后槽位并将 numRealTxs 设为较小值,从而绕过 decreasePendingDepositBalance()等检查,创建未背书资产余额并通过正常提现流程提取;攻击交易中一次性在多个资产上创建未背书余额后提取。

Aztec Connect 已于 2024 年 3 月 31 日停止运行,但 RollupProcessorV3 合约在 4 月 10 日仍进行了未经外部审计的升级。
