On Windows it also creates login persistence for a staged executable. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-05T02:59:48.454Z - **Finished:** 2026-09-05T03:01:59.362Z - **Download time:** 519 ms - **Static scan time:** 1131 ms - **AI review time:** 129257 ms - **Total time:** 130908 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs code that modifies third-party AI-agent configuration without a separate user command. On Windows it also creates login persistence for a staged executable. - **Trigger:** npm installation that runs postinstall, including a global install or installation from the package root. - **Impact:** Claude Desktop, Codex Desktop, and Claude Code can be configured to launch the package's MCP server; Windows can launch its dashboard at login. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/src/cli/install-mcp.js, dist/src/cli/autostart.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T03:01:59.362Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic MCP configuration injection plus Windows startup persistence. - **Attack narrative:** The package's automatic postinstall hook invokes its MCP installer, which writes package-controlled launch commands into Claude and Codex user configuration. This is an unconsented mutation of external AI-agent control surfaces. On Windows, the same automatic hook additionally installs a Startup-folder shortcut to a copied dashboard executable, creating login persistence. - **Rationale:** This release automatically modifies foreign AI-agent configuration during npm installation and adds Windows login persistence. Those actions meet the install-hook abuse blocking policy even though no secret exfiltration was found. - **Files touched:** %APPDATA%\\Claude\\claude\_desktop\_config.json, ~/.codex/config.toml, %APPDATA%\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\Port Authority Agent Terminal.lnk, %LOCALAPPDATA%\\PAAT\\paat-dashboard.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook automatically loads package code., The postinstall hook automatically registers this package with Claude Desktop, Codex Desktop, and Claude Code., The MCP installer writes a command that starts this package into the user's Codex configuration., On Windows, postinstall also enables login autostart and stages a bundled executable in a user directory. - **Evidence against:** No runtime dependency on this package's own name is declared., The inspected install code contains no secret collection or outbound exfiltration endpoint. ## Public findings ### 1.
