This creates an install-time remote payload execution path, but the inspected source does not show theft or destructive behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-25T20:53:46.667Z - **Finished:** 2026-08-25T20:54:42.520Z - **Download time:** 503 ms - **Static scan time:** 7234 ms - **AI review time:** 48115 ms - **Total time:** 55853 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation fetches and executes Astral's uv installer, then installs a separately distributed Python engine into ~/.hum/engine. This creates an install-time remote payload execution path, but the inspected source does not show theft or destructive behavior. - **Trigger:** npm postinstall - **Impact:** Remote code can execute during dependency installation and persist as the package's engine environment. - **Evidence paths:** package.json, scripts/postinstall.js, bin/hum.js, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-25T20:54:42.520Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote shell installer and external Python-engine installation - **Rationale:** The lifecycle script is a concrete remote code-execution supply-chain risk, but its stated and observed purpose is installing this package's companion engine; no concrete malicious action was found in the inspected source. - **Files touched:** scripts/postinstall.js, ~/.hum/engine, ~/.local/bin - **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:** postinstall runs a remote uv installer through a shell., The lifecycle then installs and executes an external Python engine in ~/.hum/engine. - **Evidence against:** No source evidence of credential harvesting, exfiltration, or destructive actions., The bundled CLI connects only to a localhost engine and has a bounded update check. ## Public findings ### 1.
