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 startup-time installation of bundled skills into OpenCode configuration is a real agent extension lifecycle risk and supports a warning. The inspected source does not establish a concrete attack, and the flagged credential examples use their intended service endpoints.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
OpenCode loads the plugin and runs its setup or server startup.
Impact
Bundled skill capabilities become available in the user’s OpenCode configuration without a separate setup command.
Mechanism
The startup pipeline installs bundled skill content in a configuration vault and generates pointers that the model can load through the skill tool.
AI rationale
The startup-time installation of bundled skills into OpenCode configuration is a real agent extension lifecycle risk and supports a warning. The inspected source does not establish a concrete attack, and the flagged credential examples use their intended service endpoints.

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 manifest defines prepublishOnly as a build command; it shows no npm install lifecycle hook.
- Plugin setup runs a startup pipeline that creates the OpenCode skills directory and invokes the skill installer.
- The pipeline installs bundled skills in a user configuration vault and generates pointers; a pointer is visible to the model after the skill tool loads it.
- The Apify helper reads APIFY_TOKEN and uses it for a request to api.apify.com with the caller-provided actor.
- The Hugging Face example optionally sends HF_TOKEN as a bearer token to huggingface.co.
Evidence against
- The inspected credential examples send tokens to their corresponding services, not to an unrelated recipient.
- The identified startup behavior installs the package’s bundled skills; the inspected source does not establish credential theft or another concrete attack.
