No confirmed credential theft, exfiltration, destructive action, or foreign agent-control mutation was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-25T21:32:18.715Z - **Finished:** 2026-08-25T21:33:18.431Z - **Download time:** 514 ms - **Static scan time:** 7041 ms - **AI review time:** 52161 ms - **Total time:** 59716 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm installation, the package downloads and executes uv's remote installer when uv is absent, then provisions a Python engine under ~/.hum. No confirmed credential theft, exfiltration, destructive action, or foreign agent-control mutation was found. - **Trigger:** npm postinstall; native CLI update path at runtime - **Impact:** A network-controlled installer and external Python package execute during installation, creating a supply-chain risk. - **Evidence paths:** package.json, scripts/postinstall.js, bin/hum.js, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-25T21:33:18.431Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote installer piping and Python engine provisioning - **Rationale:** The package has a real install-time remote-code supply-chain risk, warranting a warning. Source inspection does not establish malicious intent or a concrete malicious payload. - **Files touched:** scripts/postinstall.js, dist/cli.mjs, ~/.hum/engine, ~/.hum/update.json, ~/.hum/update.log - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh, https://storage.googleapis.com/hum-dist ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for:** postinstall executes a remotely downloaded uv installer through a shell., postinstall creates ~/.hum/engine and installs hum-cli from PyPI., The bundled CLI includes a native-layout background updater that executes a remote installer. - **Evidence against:** No credential harvesting or exfiltration was found in inspected package sources., The lifecycle action is package-aligned engine provisioning, not a foreign AI-agent control-surface mutation., The npm CLI layout only displays an update command rather than auto-running it. ## Public findings ### 1.
