A dependency installation changes a foreign AI-agent command surface and user startup environment without a separate setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.6.30 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically installs a separate global Claude Code CLI if it is absent. It also persists PATH changes and installs a desktop launcher that starts the bundled application. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-09-03T18:26:11.167Z - **Finished:** 2026-09-03T18:27:17.063Z - **Download time:** 1030 ms - **Static scan time:** 127 ms - **AI review time:** 64737 ms - **Total time:** 65896 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically installs a separate global Claude Code CLI if it is absent. It also persists PATH changes and installs a desktop launcher that starts the bundled application. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** A dependency installation changes a foreign AI-agent command surface and user startup environment without a separate setup command. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T18:27:17.063Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global agent CLI installation and persistent user-environment mutation. - **Attack narrative:** On npm installation, package.json launches postinstall. That code provisions a Python environment, installs the bundled wheel, installs @anthropic-ai/claude-code globally when Claude is missing, and calls a helper that appends PATH startup entries. It also creates a desktop application launcher. These changes occur without a separate user setup action and mutate a foreign AI-agent CLI plus persistent user control surfaces. - **Rationale:** This is a concrete install-hook abuse chain: an npm postinstall silently installs a separate global AI-agent CLI and persists environment changes. The lack of direct credential theft does not neutralize the unconsented foreign control-surface mutation. - **Files touched:** ~/.agent-takkub/venv, ~/.zshrc, ~/.bashrc, HKCU\\Environment\\Path, ~/Desktop/Takkub Cockpit.app, ~/Applications/Takkub Cockpit.app ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall program., Postinstall installs the separate Anthropic Claude Code CLI globally when absent., Postinstall persistently changes shell PATH settings and creates a desktop application launcher without a separate user command., The installer provisions and executes a bundled Python wheel during installation. - **Evidence against:** The inspected JavaScript installer does not directly read credentials or send collected data to a remote host., The installer states that it leaves existing Claude plugin and Takkub configuration files untouched. ## Public findings ### 1.
