## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 21 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Persistence
- **Selected version:** 0.12.1
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Installation automatically registers the router for execution at subsequent user logins. This establishes a persistence risk, but inspected source does not establish a malicious attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Installation automatically registers the router for execution at subsequent user logins. This establishes a persistence risk, but inspected source does not establish a malicious attack.

- **Trigger:** Installation with lifecycle scripts enabled and KCGRouter\_SKIP\_STARTUP unset, followed by user login.

- **Impact:** The package can run persistently after installation without a separate startup opt-in.

- **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/index.ts, src/cli/daemon.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-10-02T23:57:23.699Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The install hook writes operating-system startup entries that invoke the router's daemon command, which launches its server in the background.

- **Rationale:** Default install-time login persistence creates a concrete risk despite being aligned with the router's functionality. Source inspection supports a warning, while scanner similarity labels alone do not justify a malware block.

- **Files touched:** kcgrouter-startup.vbs, com.kcgrouter.plist, kcgrouter.desktop

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json automatically runs scripts/postinstall.mjs after installation., The install hook enables login startup by default unless KCGRouter\_SKIP\_STARTUP is set., The hook creates Windows Startup, macOS LaunchAgent, or Linux autostart entries for the router., The --daemon command starts src/index.ts as a detached background process.

- **Evidence against:** Startup entries launch the package's own router; explicit removal commands are available., Inspected source did not establish credential theft, remote payload execution, or foreign AI-agent control-surface mutation., The version service queries the package's npm registry metadata and supplies an update command without executing it.

## Affected versions and remediation

This report applies to kcgrouter@0.12.1.

- Review the evidence and your use of kcgrouter@0.12.1 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
