Shai-Hulud 2.0: Responding to the npm Worm Threatening CI/CD Security

**Executive Summary:** Shai-Hulud 2.0 is a self‑replicating npm/GitHub worm that steals environment variables, GitHub tokens, and cloud credentials, uses stolen credentials to re‑upload itself across maintainers' package libraries, and may delete files if attacker infrastructure is removed; the report states over 1,000 npm packages and 27,000+ GitHub repositories were infected within hours and provides immediate remediation steps for developers and CI/CD pipelines.
