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
SuspiciousIndependent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree.
The npm package has no install hook, but its OpenCode setup and server hooks automatically publish bundled skills into the active agent skill surface. This matches an agent extension lifecycle risk, while the inspected network and credential findings do not establish a separate attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
OpenCode loads the installed plugin and calls its setup or server hook.
Impact
Bundled skill instructions become available to the agent without a separate per-skill approval. No credential theft or other concrete malicious behavior was established.
Mechanism
The plugin reads the bundled index, applies the user’s filter configuration, copies selected skill folders into the OpenCode skill library, and writes category pointers into the active skills directory.
AI rationale
The npm package has no install hook, but its OpenCode setup and server hooks automatically publish bundled skills into the active agent skill surface. This matches an agent extension lifecycle risk, while the inspected network and credential findings do not establish a separate attack.

Independent scan evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for AI warning decision
- The plugin runs its startup routine during both setup and server startup.
- That routine filters the bundled skill index and copies included skills into the OpenCode skill library.
- The default filter excludes no risk levels; a bundled community skill is marked critical.
- The plugin writes category pointers into the active skills directory, making bundled skills available to the agent.
- The npm lifecycle script is prepublishOnly and runs only the build.
- The inspected Apify and Hugging Face examples send caller-provided environment tokens to their matching services.
Evidence against
- The inspected token handling is service-aligned, and the Apify example starts only after a token is supplied and an actor is selected.
- The plugin copies skill files; the inspected startup path does not execute their scripts or send network requests.
