Self Propagating npm Supply Chain Attack Targeting Developer Tokens
A new and active npm supply‑chain attack has been observed abusing compromised maintainer credentials to self‑propagate malicious code across packages in the Node.js ecosystem. The malware steals authentication material (npm tokens, cloud credentials, CI/CD secrets, SSH keys, and wallet data) and uses any discovered publishing tokens to inject itself into additional packages owned by the same maintainer, creating worm‑like lateral spread.
