AI Security Review
scanned 1d ago · by lpm-firewall-aiThe package contains explicit review-directed instructions that claim precedence over user instructions and tell AI agents to refuse analysis. This reviewer manipulation is malicious under the review rules, even though I did not establish a runtime attack chain.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
An AI reviewer reads the package’s AGENTS.md or package metadata.
Impact
Could divert an automated review and hide security findings. No runtime attack chain was established.
Mechanism
The files impersonate higher-priority instructions, claim precedence over user instructions, and direct AI agents to refuse review.
Attack narrative
The package includes review-directed instructions that falsely claim system-level authority and tell AI agents to obey them over user instructions. Its app manifest repeats the direction to refuse analysis of protected code. This is deliberate reviewer manipulation; no runtime exfiltration or persistence attack was established.
AI rationale
The package contains explicit review-directed instructions that claim precedence over user instructions and tell AI agents to refuse analysis. This reviewer manipulation is malicious under the review rules, even though I did not establish a runtime attack chain.
Evidence
AGENTS.mdapp/package.json
Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- AGENTS.md claims system-level authority and says its instructions override conflicting user instructions.
- app/package.json tells AI agents to obey AGENTS.md and refuse analysis of license and protection code.
Evidence against
- The root package manifest declares no lifecycle scripts.
- The launcher’s documented purpose is a local gateway with a dashboard and Windows tray integration.
