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 OpenCode extension that mutates an agent control surface at runtime, warranting a warning. Static inspection found no install hook, self-dependency, credential theft, or package-runtime network behavior that would justify blocking.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Loading the installed OpenCode plugin during OpenCode startup.
Impact
The package can alter the agent's available skills and remove matching managed pointer directories.
Mechanism
User-level agent skill installation and pointer-directory cleanup.
AI rationale
This is a first-party OpenCode extension that mutates an agent control surface at runtime, warranting a warning. Static inspection found no install hook, self-dependency, credential theft, or package-runtime network behavior that would justify blocking.

Independent scan evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for AI warning decision
- The OpenCode plugin runs on startup and populates the user's OpenCode skills directory.
- It recursively deletes stale category-pointer directories and overwrites its managed pointer files.
- It copies the bundled skill collection into a user-level OpenCode vault, making its instructions available to the agent.
Evidence against
- package.json has only a prepublish hook, so registry installation does not run package code.
- The plugin runtime contains no outbound network request or credential collection.
- The flagged Apify, Hugging Face, and Playwright utilities are separate examples invoked explicitly; their network, token, and install actions are not reached by the plugin.
