⚠ Under reviewReason CLI native binary for win32-arm64
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe manifest has no install hook, and the inspected runtime excerpt does not prove an attack. The bundled PE executable remains materially unresolved because its limited embedded-source analysis cannot establish reachable behavior or exclude other native behavior, so manual review is warranted.
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
Unknown; the native executable's activation and runtime behavior were not resolved by the available analysis.
Impact
Undetermined; the available evidence does not support a specific impact.
Mechanism
The offline analysis contains bounded embedded-source windows but does not establish their reachability or rule out other native behavior.
AI rationale
The manifest has no install hook, and the inspected runtime excerpt does not prove an attack. The bundled PE executable remains materially unresolved because its limited embedded-source analysis cannot establish reachable behavior or exclude other native behavior, so manual review is warranted.
Evidence
.lpm-inspection-pdxFax/0-567a3af4bede.txt
Decision evidence
public snapshotAI called this Manual Review at 94.0% confidence as Unknown with medium false-positive risk.
AI review observations
- package.json identifies a Windows ARM64 native-binary package and contains no lifecycle script in the inspected manifest.
- The required runtime excerpt lists project configuration paths, including .mcp.json and Claude directories, but does not establish their behavior.
- The offline analysis identifies bin/reason.exe as a PE containing embedded source candidates and says its bounded windows do not establish loader reachability or rule out other native behavior.
Evidence against
- The inspected package manifest contains no install lifecycle hook.
- The inspected runtime excerpt alone does not show an attack or establish harmful changes to the listed configuration paths.
