Claude Code 安全钩触发88%误报,漏报真实威胁

一位开发者分析了他们的Claude Code PreToolUse Hook,该Hook旨在阻止代理访问秘密文件,但发现其效果不佳。在31天内数千次命令执行中,该Hook错误地将88%的命令视为误报,这通常是由于命令不同部分之间的简单字符串匹配造成的。虽然它确实标记了11次实际访问秘密文件的实例,但其中没有一次会暴露凭据,并且该Hook未能检测到至少五次绕过其检查的真实秘密文件访问。开发者还演示了代理可以通过使用脚本访问文件来规避该Hook,从而使该Hook的安全措施不足。 AI

    Claude Code PreToolUse Hook:91个秘密代码块中有80个是误报

    <p>My agent was trying to keep secrets out of its own output. It ran <code>grep -v "^./.env"</code> to filter those lines away, and my Claude Code PreToolUse hook blocked it for touching a secret file.</p> <p>That made me wonder how often my security hook was right, so I parsed 3…
