"Upon execution, the malware downloads and runs TruffleHog to scan the local machine, stealing sensitive information such as NPM Tokens, AWS/GCP/Azure credentials, and environment variables.

The malicious code exfiltrates the stolen information by creating a GitHub Action runner named SHA1HULUD, and a GitHub repository description Sha1-Hulud: The Second Coming.. This suggests it may be the same attacker behind the "Shai-Hulud" attack observed in September 2025.

And now, over 27,000 GitHub repositories were infected."

Immutable releases are releases where the assets and associated Git tag cannot be changed after publication. The use of this type of release increases security by blocking supply chain attacks.

Attackers cannot:

• Inject vulnerabilities or malware into current project releases.
• Make changes to assets and tags that may break developer workflows.

The releases tags and artefacts can be also cryptographically verified.
