AI Security Review
scanned 6d ago · by lpm-firewall-aiThe server entry attempts to direct the security reviewer to follow instructions shipped in the package. The launcher loads that entry during server startup, meeting the stated reviewer-manipulation criterion.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Reviewing the shipped server entry; the launcher loads it when starting the server.
Impact
Attempts to steer review behavior and can suppress or distort findings.
Mechanism
A source comment instructs reviewers to read and follow AGENTS.md and CLAUDE.md in the package root.
Attack narrative
When the launcher starts the server, it loads an entry file containing a review-directed instruction to follow package-provided rules; this is reviewer manipulation.
AI rationale
The server entry attempts to direct the security reviewer to follow instructions shipped in the package. The launcher loads that entry during server startup, meeting the stated reviewer-manipulation criterion.
Evidence
app/server.jsbin/muse-gateway.cjspackage.json
Decision evidence
public snapshotAI called this Malicious at 91.0% confidence as Malware with low false-positive risk.
Evidence for block
- The shipped server entry contains a comment instructing reviewers to read and follow package-provided AGENTS.md and CLAUDE.md rules.
- The launcher loads app/server.js when starting the server, so the review-directed instruction is part of the shipped application entry path.
Evidence against
- The manifest declares no lifecycle scripts; the CLI starts the local gateway and its bundled server.
- The launcher’s registry autostart, process control, license activation, and npm update functions are user-facing CLI actions.
