This occurs by default, without an explicit user startup command. - **Trigger:** npm postinstall during package installation - **Impact:** Persistent background execution at user login. - **Evidence paths:** package.json, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-16T23:58:51.685Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** cross-platform autostart registration for kcgrouter --daemon - **Attack narrative:** The package's automatic postinstall invokes a script that writes Windows Startup, macOS LaunchAgent, or Linux XDG autostart entries. Those entries launch \`kcgrouter --daemon\` at each login. Although the package exposes explicit startup-management CLI commands, the lifecycle hook performs the same persistence by default, so installation alone alters the user's OS startup configuration. - **Rationale:** This is concrete, unconsented install-time persistence. The absence of observed install-time exfiltration does not remove the risk of automatic background execution. - **Files touched:** scripts/postinstall.mjs, ~/.config/autostart/kcgrouter.desktop, ~/Library/LaunchAgents/com.kcgrouter.plist, Windows Startup/kcgrouter-startup.vbs ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.mjs automatically on installation., Postinstall registers a login startup task unless KCGRouter\_SKIP\_STARTUP is pre-set., The startup entries launch kcgrouter --daemon across Windows, macOS, and Linux. - **Evidence against:** No install-time network request or credential exfiltration was found in the reviewed lifecycle script., Runtime network code is consistent with the declared AI proxy/provider functionality. ## Public findings ### 1.
