No confirmed AI-agent configuration hijack, credential theft, or exfiltration was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-07-11T12:48:46.927Z - **Finished:** 2026-07-11T12:49:58.275Z - **Download time:** 254 ms - **Static scan time:** 375 ms - **AI review time:** 70717 ms - **Total time:** 71348 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code provisions an isolated Python application, may install the Claude CLI globally, persists PATH changes, and creates a Desktop launcher. No confirmed AI-agent configuration hijack, credential theft, or exfiltration was found. - **Trigger:** \`npm install\` / \`npm install -g agent-takkub\` - **Impact:** Creates user-home application state and alters command availability without an explicit follow-up command. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, npm/scripts/preflight.js, dist/agent\_takkub-1.0.23-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-07-11T12:49:58.275Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall environment provisioning and persistent user-environment mutation - **Rationale:** The postinstall behavior is intrusive and network-capable through package managers, so it warrants a warning. Source inspection does not substantiate the scanner's claimed AI-agent control-surface hijack or a concrete malicious chain. - **Files touched:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, dist/agent\_takkub-1.0.23-py3-none-any.whl, ~/.agent-takkub/venv, ~/.zshrc, ~/.bashrc ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`package.json\` runs \`postinstall\`., \`npm/scripts/postinstall.js\` creates \`~/.agent-takkub/venv\` and installs the bundled wheel., Postinstall globally installs \`@anthropic-ai/claude-code\` when \`claude\` is absent., \`npm/scripts/pathfix.js\` persistently edits the user PATH (\`HKCU\\Environment\` or shell rc files)., \`npm/scripts/shortcut.js\` creates a Desktop launcher. - **Evidence against:** Postinstall states and source confirms no writes to \`~/.claude\` plugins or \`~/.takkub\` config., Bundled wheel is installed locally; no hidden downloader or encoded payload execution found., Plugin/MCP installation code in \`agent\_takkub/plugin\_installer.py\` is runtime UI/CLI functionality, not postinstall., No credential harvesting or concrete exfiltration endpoint found in inspected installer paths. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
