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.

The inspected runtime and flagged examples do not establish malicious behavior. The PDF’s structure remains unverified despite its view-only catalog use, so manual review is warranted.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

The PDF is presented when a user views the theme catalog.

Impact

Whether the PDF contains embedded behavior is unknown; no attack impact is confirmed.

Mechanism

The available offline analysis could not inspect the PDF’s structure or executable content.

AI rationale

The inspected runtime and flagged examples do not establish malicious behavior. The PDF’s structure remains unverified despite its view-only catalog use, so manual review is warranted.

Evidence

bundled-skills/theme-factory/theme-showcase.pdf.lpm-inspection-VvFCac/0-3e126eca9fe9.txt

Independent scan evidence

public snapshot

AI called this Manual Review at 86.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest points to dist/index.js; its setup runs the startup pipeline, which copies bundled skills into the OpenCode skill vault.
The theme instructions use theme-showcase.pdf as a view-only catalog, but the offline analysis could not determine whether the PDF contains executable or embedded content.
The flagged Apify example sends its token to api.apify.com, and the Hugging Face example sends its optional token to huggingface.co.

Evidence against

The manifest’s only lifecycle script is prepublishOnly, which runs the build.
The inspected Apify and Hugging Face requests target their respective services; no unrelated credential recipient was identified.
The PDF is described as a visual catalog, but its structure remains unverified.
