## Security analysis

### Published attack-surface review

- **Summary:** Installing the package runs code that installs automatic user-login launch entries. It persists a daemon without an explicit setup command or interactive consent.

- **Trigger:** npm installation executes postinstall.

- **Impact:** The package starts its daemon automatically at future user logins.

- **Evidence paths:** package.json, scripts/postinstall.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-31T23:59:58.732Z

### AI review details

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

- **Mechanism:** Cross-platform login persistence through startup folders, LaunchAgents, and XDG autostart.

- **Attack narrative:** The manifest invokes scripts/postinstall.mjs during installation. Unless KCGRouter\_SKIP\_STARTUP is already set, the script creates a Windows Startup entry, macOS LaunchAgent, or Linux XDG autostart file that launches kcgrouter as a daemon at login. This is unconsented persistence performed automatically at install time.

- **Rationale:** This package uses an automatic npm lifecycle hook to establish cross-platform login persistence. The behavior is concrete and does not require the user to invoke the documented startup command.

- **Files touched:** scripts/postinstall.mjs, ~/Library/LaunchAgents/com.kcgrouter.plist, ~/.config/autostart/kcgrouter.desktop, %APPDATA%/Microsoft/Windows/Start Menu/Programs/Startup/kcgrouter-startup.vbs

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** The npm postinstall hook automatically runs a package script., That script creates login-start persistence on Windows, macOS, and Linux unless an environment variable is set., The macOS LaunchAgent is configured to run the kcgrouter daemon at load.

- **Evidence against:** No install-time network request or credential collection was found in the inspected lifecycle script., The runtime provider requests are consistent with the stated proxy function, not evidence of install-time exfiltration.
