Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package runs a postinstall script that creates an operating-system login startup entry. The persisted entry launches a detached kcgrouter daemon and uses process renaming intended to evade broad cleanup. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T23:53:19.858Z - **Finished:** 2026-09-13T23:54:22.388Z - **Download time:** 1015 ms - **Static scan time:** 1965 ms - **AI review time:** 59549 ms - **Total time:** 62530 ms The recorded confidence comes from the underlying analysis.

The persisted entry launches a detached kcgrouter daemon and uses process renaming intended to evade broad cleanup. - **Trigger:** npm or Bun installation runs postinstall; the daemon then starts at the next user login. - **Impact:** A package-installed daemon can execute automatically at every user login without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/daemon.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-13T23:54:22.388Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unconsented install-time OS startup persistence with process-name evasion. - **Attack narrative:** On installation, package.json invokes scripts/postinstall.mjs. Unless the installer already set a package-specific opt-out variable, that code writes a Windows Startup script, a macOS LaunchAgent, or a Linux XDG autostart entry that launches kcgrouter with --daemon. The daemon is detached and its runtime is renamed to kcgrouterd; on Windows it copies Bun to kcgrouterd.exe. The source states this is to resist AI-agent and cleanup tools that kill Bun processes. - **Rationale:** This is concrete unconsented install-time persistence across operating systems, reinforced by deliberate process-name evasion. The absence of a self-dependency does not neutralize this lifecycle abuse. - **Files touched:** scripts/postinstall.mjs, src/cli/daemon.ts, %APPDATA%/Microsoft/Windows/Start Menu/Programs/Startup/kcgrouter-startup.vbs, ~/Library/LaunchAgents/com.kcgrouter.plist, ~/.config/autostart/kcgrouter.desktop, ~/.kcgrouter/server.pid, ~/.kcgrouter/server.log, ~/.kcgrouter/kcgrouterd.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The install lifecycle automatically registers a login-start persistence mechanism unless an environment variable is set., The installer writes startup entries for Windows, macOS, and Linux, causing the package daemon to run at login., Daemon code deliberately renames or copies its runtime as kcgrouterd to avoid cleanup tools, explicitly including AI-agent cleanup tools. - **Evidence against:** The package has no runtime dependency on its own package name., The inspected provider network code is a user-configured connection test, not an install-time exfiltration path. ## Affected versions and remediation This report applies to kcgrouter@0.14.2. - Avoid installing kcgrouter@0.14.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
