Advisory
MAL-2026-18193
Source
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 source verifies automatic setup of a package-owned OpenCode skill extension, which is warning-level under the review policy. The manifest has no registry install hook, and the inspected source does not establish a concrete attack chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
OpenCode invokes the plugin setup or server entrypoint.
Impact
Bundled instructions become available to the OpenCode agent, and the plugin manages its library entries and generated pointers.
Mechanism
The startup pipeline copies bundled skill folders into the skill-library vault and writes category pointer files in the active skills directory.
AI rationale
The source verifies automatic setup of a package-owned OpenCode skill extension, which is warning-level under the review policy. The manifest has no registry install hook, and the inspected source does not establish a concrete attack chain.

Independent scan evidence
public snapshotAI called this Suspicious at 80.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for AI warning decision
- The manifest has a prepublish build hook, not an install hook.
- OpenCode plugin setup runs the startup pipeline.
- The pipeline installs bundled skills into a vault and applies configured patches.
- The installer removes vault entries that are absent from its bundled index.
- The installer copies bundled skill folders into the vault.
- The plugin writes category pointers into OpenCode's active skills directory.
Evidence against
- The inspected Apify example uses a caller-provided token to run the selected actor through api.apify.com.
- The inspected theme instructions use the PDF as a visual reference.
