Palo Alto Unit 42 于2026年6月2日更新了关于 npm 供应链威胁格局的报告。报告指出，自 Shai Hulud 事件以来，npm 生态系统面临的攻击面持续演化，出现了可蠕虫式传播的恶意软件、针对 CI/CD 管道的持久化机制以及多阶段攻击等新型威胁。这些攻击通常利用软件包依赖关系、混淆技术以及自动化构建流程中的漏洞，在开发者环境中植入后门，进而影响下游用户。报告强调了 npm 作为关键软件供应链环节的脆弱性，并讨论了包括包签名验证、依赖审计、最小权限原则、CI/CD 安全加固在内的缓解措施。尽管未披露具体样本或 IOC，但该分析为安全团队理解当前 npm 威胁态势提供了重要参考。
💡 影响/原因: npm 是 JavaScript/Node.js 生态的核心包管理器，其供应链攻击可影响大量应用和开发者，且蠕虫式传播与 CI/CD 持久化手段使得威胁扩散更快、更隐蔽。
🎯 建议动作: 1. 实施严格的包依赖审核，使用锁文件（package-lock.json）并定期扫描已知漏洞。2. 在 CI/CD 管道中采用最小权限原则，隔离构建环境并审计第三方操作。3. 部署运行时安全监控，检测异常包行为。4. 启用 npm 的完整性验证（如 PGP 签名）并启用双重认证。5. 教育开发者识别社会工程学攻击，避免安装可疑包。
