AI Security Review
scanned 14d ago · by lpm-firewall-aiThe published entry point is heavily obfuscated, and static inspection did not resolve its full behavior. The inspected network code shows DNS resolver use, but no concrete attack chain; warn rather than block.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the package CLI or importing its main entry point.
Impact
No malicious effect was confirmed, but the opaque executable warrants a warning.
Mechanism
The entry point is heavily obfuscated, limiting static verification; the inspected DNS code selects public resolver endpoints.
AI rationale
The published entry point is heavily obfuscated, and static inspection did not resolve its full behavior. The inspected network code shows DNS resolver use, but no concrete attack chain; warn rather than block.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The manifest exposes a bundled executable as both the package entry point and CLI.
- The executable bundle begins with a large obfuscated string-table rotation loop, which leaves its behavior difficult to verify.
- The MCP bundle includes DNS-over-HTTPS endpoint selection and environment-based configuration; the inspected excerpt does not show credential collection or an exfiltration sink.
Evidence against
- The manifest declares no install lifecycle scripts.
- The inspected network code uses public DNS-over-HTTPS resolvers and does not establish an attack.
