ChainCatcher 消息，据 Arbitrum 安全委员会报告，为应对日益复杂的 AI 辅助攻击风险，Arbitrum 已于北京时间 10 月 2 日 23:30 左右采取紧急行动，暂时阻止 Arbitrum One 和 Nova 网络上新的 Stylus 合约激活。
此次限制主要针对需要全新激活的程序及应用更新，而已激活的 Stylus 应用可继续运行，普通的 Solidity 合约部署与执行不受影响。Arbitrum 官方表示，此次预防性措施源于针对非标准 Stylus 编译器工具链的 WebAssembly 程序攻击威胁，目前尚未发现资金被盗风险，主要担忧在于链上活跃度及拒绝服务（DoS）攻击。开发者仍可通过无需许可的保活续期机制延长现有程序的生命周期，但无法激活过期程序或新版本应用。
