It affects Windows, macOS, and Linux unless the installer environment already sets an opt-out variable. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** The package can start persistently in the user session without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T00:03:33.501Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic OS login-startup registration and hidden daemon launch. - **Attack narrative:** The package's postinstall hook runs automatically during installation. Unless the installer pre-sets KCGRouter\_SKIP\_STARTUP, it creates a Windows Startup-folder launcher, a macOS LaunchAgent, or a Linux XDG autostart entry. Those entries launch the package daemon at user login; the Windows launcher is configured to run hidden. This is unconsented persistence established by an install hook, even though the reviewed hook does not itself send network traffic or collect credentials. - **Rationale:** The automatic postinstall hook persists a background package daemon across logins without an explicit user command. This is concrete install-hook persistence and warrants blocking despite the absence of confirmed credential exfiltration. - **Files touched:** scripts/postinstall.mjs, ~/.kcgrouter/scripts/kcgrouter-startup.vbs, %APPDATA%/Microsoft/Windows/Start Menu/Programs/Startup/kcgrouter-startup.vbs, ~/Library/LaunchAgents/com.kcgrouter.plist, ~/.config/autostart/kcgrouter.desktop ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall script., Postinstall registers startup persistence unless an opt-out variable is already set., The installer writes operating-system startup entries that launch kcgrouter at login., On Windows it drops a hidden VBS launcher into the user Startup folder. - **Evidence against:** No self-dependency is declared., The reviewed lifecycle script contains no network request or credential collection., Reviewed provider requests are runtime connection tests using configured provider credentials. ## Public findings ### 1.
