OpenSSF Malicious Packages via OSV

Summary

Malicious code in opencode-skills-collection (npm)

Details

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Independent LPM AI assessment

Manual Review

Independent AI assessment: manual_review. LPM AI review remains unresolved.

Verified text source was inspected, but required binary or non-UTF8 files remain unresolved: bundled-skills/theme-factory/theme-showcase.pdf. A clean verdict cannot be grounded.

Static reason

High-risk behavior combination matched malicious policy.

AI rationale

Verified text source was inspected, but required binary or non-UTF8 files remain unresolved: bundled-skills/theme-factory/theme-showcase.pdf. A clean verdict cannot be grounded.

Independent scan evidence

public snapshot

AI called this Manual Review at 50.0% confidence as Unknown with medium false-positive risk.

AI review observations

The only manifest lifecycle script is prepublishOnly, which runs the build.
The signup skill contains ordinary UX guidance.
The Playwright runner executes code supplied by its caller; the Electron drive sends commands to a loopback service.
The Apify example reads APIFY_TOKEN and sends it to api.apify.com for the actor selected by the caller.
The Hugging Face example sends HF_TOKEN to huggingface.co, its intended service.
The PDF is documented as a viewing asset; the Fedora test uses a temporary HOME, and the research workflow receives a user-provided question.
