The update path can also reinstall the package globally with the persistence setup enabled. - **Trigger:** npm install or update; later application update handling - **Impact:** A remotely supplied application and persistent local daemon can run without a separate explicit setup action. - **Evidence paths:** package.json, scripts/postinstall-app.mjs, scripts/postinstall-control-plane.mjs, scripts/apply-pending-update.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-28T18:20:59.298Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time persistence plus remote binary replacement and self-reinstallation - **Rationale:** The postinstall creates persistent execution and imports a remote application payload, while a later updater recursively reinstalls the lifecycle-enabled package. This exceeds ordinary package setup and creates a concrete install-hook abuse path. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist, trace-mcp.app, .trace-mcp-pending.zip, .trace-mcp-version - **Network endpoints:** api.github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for:** The npm postinstall runs two scripts that alter user-level runtime state., On macOS, postinstall writes and bootstraps a launchd service configured to run at load and stay alive., Postinstall fetches the latest release asset, verifies a checksum fetched from the same release channel, extracts it, and replaces an installed application., The updater can invoke npm to globally install another trace-mcp version and deliberately re-enables its postinstall control-plane setup. - **Evidence against:** The inspected lifecycle code contains no credential harvesting or secret exfiltration., The downloaded archive name is restricted and extraction uses an argument-based process call rather than a shell. ## Public findings ### 1.
