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 package has no install-time hook, but its plugin startup automatically changes OpenCode skill configuration by installing bundled agent skills. This is package-aligned extension setup, so warn without blocking publication.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
OpenCode loads the plugin and calls its setup or server entrypoint.
Impact
Bundled agent capabilities become available through OpenCode configuration without a separate per-skill setup action; no credential theft or unrelated data transfer was confirmed.
Mechanism
The startup pipeline installs package-bundled skill folders and writes category pointer files under the user’s OpenCode configuration.
AI rationale
The package has no install-time hook, but its plugin startup automatically changes OpenCode skill configuration by installing bundled agent skills. This is package-aligned extension setup, so warn without blocking publication.
Evidence

Independent scan evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for AI warning decision
- package.json points to dist/index.js and declares only a prepublishOnly build script.
- The plugin runs its startup pipeline from setup and server entrypoints, populating the OpenCode skill vault and active skills directory.
- The pipeline copies bundled skills into the vault and writes category pointers into the active skills directory.
- The flagged Apify and Hugging Face examples use credentials with their corresponding services.
Evidence against
- The startup writes are limited to this plugin’s OpenCode skill vault and generated pointer directories; no install-time hook or unrelated network transfer was established.
