At the next login, it launches the package's detached daemon without an explicit user command. - **Trigger:** npm installation, followed by user login - **Impact:** The package persists and starts a local server automatically across user logins. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/index.ts, src/cli/daemon.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-01T00:03:35.297Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall startup persistence that launches a detached daemon - **Attack narrative:** The npm postinstall hook runs without a separate setup command and creates platform-specific login-startup entries. Those entries invoke kcgrouter with --daemon. The CLI resolves that flag by starting a detached production server process, allowing the package to persist and run after future logins. - **Rationale:** This is concrete unconsented install-time persistence, not merely an explicit user-requested startup option. The automatic cross-platform login registration and detached daemon launch justify blocking publication. - **Files touched:** scripts/postinstall.mjs, src/cli/index.ts, src/cli/daemon.ts, ~/Library/LaunchAgents/com.kcgrouter.plist, ~/.config/autostart/kcgrouter.desktop, Windows Startup/kcgrouter-startup.vbs ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall script automatically., Postinstall writes OS login-startup entries on Windows, macOS, and Linux., The generated startup command invokes the package with --daemon., The daemon detaches a production server process and records its PID. - **Evidence against:** No credential harvesting or unrelated network exfiltration was confirmed in the inspected paths., Provider API requests are part of the stated proxy functionality and are not needed for the persistence finding. ## Public findings ### 1.
