No foreign AI-agent configuration mutation or exfiltration was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-19T07:17:02.218Z - **Finished:** 2026-08-19T07:19:10.107Z - **Download time:** 505 ms - **Static scan time:** 101 ms - **AI review time:** 127282 ms - **Total time:** 127889 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time provisioning changes user state and can install another global CLI. No foreign AI-agent configuration mutation or exfiltration was confirmed. - **Trigger:** npm install, via postinstall - **Impact:** Unexpected global dependency installation and persistent shell/desktop changes. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, dist/agent\_takkub-1.0.75-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-08-19T07:19:10.107Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global CLI installation, wheel provisioning, PATH persistence, and launcher creation - **Rationale:** The package has a real install-hook abuse surface through global dependency installation and persistence. Its source does not demonstrate the concrete malicious chain required for a block. - **Files touched:** dist/agent\_takkub-1.0.75-py3-none-any.whl, ~/.agent-takkub/venv, ~/.zshrc, ~/.bashrc, ~/Desktop/Takkub Cockpit.app, ~/Applications/Takkub Cockpit.app ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** npm postinstall executes automatically., It installs @anthropic-ai/claude-code globally when absent., It provisions and reinstalls a bundled Python wheel in ~/.agent-takkub., It persistently amends PATH and creates a desktop application launcher. - **Evidence against:** No postinstall code writes ~/.claude, agent configs, or credentials., The bundled artifact is a Python wheel with listed source files, not an opaque executable., No concrete credential exfiltration, remote payload fetch, or AI-control hijack was confirmed. ## Public findings ### 1.
