AI Security Review
scanned 17d ago · by lpm-firewall-aiSource inspection found an install-time telemetry hook, but its actual send is gated by a saved affirmative preference and carries limited package and runtime metadata. The flagged process execution is used by login or explicit rebuild workflows; no concrete attack behavior was identified.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the package; the telemetry request proceeds only when the saved preference is true and applicable environment guards pass.
Impact
No confirmed harmful effect was established from the inspected source.
Mechanism
The hook reads the Extenshi config and posts package version and coarse runtime information to its telemetry endpoint. Other inspected process execution supports browser login or explicit source rebuild verification.
AI rationale
Source inspection found an install-time telemetry hook, but its actual send is gated by a saved affirmative preference and carries limited package and runtime metadata. The flagged process execution is used by login or explicit rebuild workflows; no concrete attack behavior was identified.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The install hook requires telemetry to be explicitly recorded as true before continuing.
- The postinstall event sends package version and coarse runtime details to the configured telemetry host.
- Browser launching occurs inside the login helper and is skipped in CI or when disabled.
- Rebuild commands run in a temporary clean room as part of the source verification helper.
- Git subprocess use is limited to local provenance inspection.
- The CLI entrypoint imports product commands; inspected smoke callbacks only collect browser error messages.
