Installs and exposes a third-party AI-agent control tool without an explicit user 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:** 1.0.69 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation automatically provisions a Python environment and installs a foreign Claude Code CLI globally if absent. It also persists PATH and launcher changes. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-16T16:02:01.231Z - **Finished:** 2026-08-16T16:02:58.357Z - **Download time:** 506 ms - **Static scan time:** 99 ms - **AI review time:** 56519 ms - **Total time:** 57126 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically provisions a Python environment and installs a foreign Claude Code CLI globally if absent. It also persists PATH and launcher changes. - **Trigger:** npm install (postinstall) - **Impact:** Installs and exposes a third-party AI-agent control tool without an explicit user command. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, dist/agent\_takkub-1.0.69-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-08-16T16:02:58.357Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic global AI-agent CLI installation plus persistent user-environment mutation - **Attack narrative:** On npm installation, the postinstall script creates or upgrades its venv and, when \`claude\` is missing, executes \`npm install -g @anthropic-ai/claude-code\`. This unconsented lifecycle action mutates a foreign AI-agent control surface. The same hook also persists PATH changes and creates a desktop launcher. - **Rationale:** The automatic global installation of Anthropic's Claude Code from this unrelated package is a concrete unconsented postinstall mutation of a foreign AI-agent control surface. This meets the install-control-surface block boundary despite no observed exfiltration. - **Files touched:** npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, dist/agent\_takkub-1.0.69-py3-none-any.whl, ~/.agent-takkub/venv, ~/.zshrc, ~/.bashrc, ~/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:** postinstall runs automatically on installation., When Claude is absent, postinstall globally installs @anthropic-ai/claude-code., The lifecycle script also persists PATH changes in shell rc files and creates a desktop app launcher. - **Evidence against:** No source evidence of credential harvesting or exfiltration was found in inspected installer code., The bundled remote server binds only to 127.0.0.1. ## Public findings ### 1.
