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.
This is a first-party agent extension that automatically modifies its own OpenCode control surface and ships powerful user-invoked tooling. The code does not establish a concrete malicious install or exfiltration chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
OpenCode loads the installed plugin at startup; individual bundled tools require explicit invocation.
Impact
It can alter the package-owned OpenCode skill library and expose high-privilege agent capabilities; no automatic credential exfiltration or install-time execution was confirmed.
Mechanism
First-party OpenCode skill synchronization and bundled user-invoked automation.
AI rationale
This is a first-party agent extension that automatically modifies its own OpenCode control surface and ships powerful user-invoked tooling. The code does not establish a concrete malicious install or exfiltration chain.

Independent scan evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for AI warning decision
- The plugin runs on OpenCode startup and writes into the user's OpenCode skills directory.
- Its synchronization deletes entries from its vault that are absent from the bundled index, then replaces bundled skill directories.
- A bundled Playwright helper writes and requires code supplied at invocation time, creating a powerful agent-execution capability.
Evidence against
- package.json has only a prepublishOnly hook, not an install-time lifecycle hook.
- The startup code does not make network requests or read environment credentials.
- The Apify and Hugging Face requests are in separately invoked reference scripts and use user-provided tokens.
- The Fedora test script uses an isolated temporary home directory.
