受影响的是读 /etc/ssl/cert.pem 的命令行工具,Safari 与 Mail 早已自动拦截
macOS 27.2 会抹掉手动修复,每次系统更新后都得重新检查再打一次
复现只需一条 git clone,证书由被攻破的 eMudhra 中间 CA 签发
苹果官方文档承认 cert.pem 的修改要等"未来的软件更新",且可能被回滚
💡 金句
Apple was notified of the eMudhra incident on 17th October. As of 28th October, the developer tools Apple ships with macOS, including git, curl and python3, still trust the compromised certificates.
