No direct theft or destructive action is visible in the reviewed Node source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-29T21:52:21.369Z - **Finished:** 2026-08-29T21:53:36.274Z - **Download time:** 774 ms - **Static scan time:** 7229 ms - **AI review time:** 66901 ms - **Total time:** 74905 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the npm package silently executes a downloaded installer and installs a separate Python engine. No direct theft or destructive action is visible in the reviewed Node source. - **Trigger:** npm postinstall - **Impact:** Remote installer or engine content executes with the installing user's permissions. - **Evidence paths:** package.json, scripts/postinstall.js, dist/install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-29T21:53:36.274Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote shell execution followed by external Python package installation. - **Rationale:** The package has a concrete, hidden install-time remote execution path, but the inspected source does not establish theft, destructive behavior, or broad AI-agent control-surface mutation. It should be warned pending trust review of the remote installer and Python engine. - **Files touched:** scripts/postinstall.js, dist/install.mjs, ~/.hum/engine, ~/.hum/engine-install.json - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall hook automatically., The hook notes that npm normally hides its activity and suppresses install failure., Install code pipes a remote uv installer directly into a shell or PowerShell., It then installs an external Python engine during npm installation. - **Evidence against:** No source evidence of credential harvesting, data exfiltration, or AI-agent configuration changes., The visible Node code limits its own state to the user's .hum directory and pins the requested engine version. ## Public findings ### 1.
