Cache-Poisoning Caper Turns TanStack Npm Packages Toxic
Researchers say 400-plus package artifacts were compromised across npm, PyPI and Composer as attackers used valid provenance to hide credential-stealing malware.
- On yesterday, attackers published 84 malicious versions across 42 TanStack packages on the Node Package Manager, each carrying valid provenance and signatures.
- This incident is part of the ongoing Shai-Hulud campaign, which has compromised hundreds of packages across Node Package Manager, PyPI, and Composer since last September.
- By hijacking valid OpenID Connect tokens, threat actors generated malicious packages with verifiable SLSA Build Level 3 attestations; Snyk researchers say the "attack produces valid SLSA Build Level 3 attestations for malicious packages."
- The payload reads GitHub Actions process memory to collect credentials from more than 100 file paths, including AWS Secrets Manager, Kubernetes service account tokens, and SSH keys.
- Researchers recommend that security teams rotate all credentials including GitHub tokens and Node Package Manager tokens, while auditing IDE directories for malicious files surviving installation.
