Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.1.63 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This is an unconsented install-time remote-code bootstrap, but the observed filesystem target is the package's own engine directory and the inspected JavaScript contains no concrete credential theft or broad agent-control mutation. It warrants a warning rather than a block under the stated lifecycle policy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-08T12:07:01.929Z - **Finished:** 2026-09-08T12:08:17.559Z - **Download time:** 507 ms - **Static scan time:** 8062 ms - **AI review time:** 67061 ms - **Total time:** 75630 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically downloads and executes external installers, then adds a Python engine under the user's .hum directory. A later user-accepted update can run a detached remote installer. - **Trigger:** npm postinstall; later, a CLI update choice. - **Impact:** A remote installer or Python package can execute with the installing user's permissions. - **Evidence paths:** scripts/postinstall.js, dist/install.mjs, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-08T12:08:17.559Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote shell bootstrap and Python engine installation. - **Rationale:** This is an unconsented install-time remote-code bootstrap, but the observed filesystem target is the package's own engine directory and the inspected JavaScript contains no concrete credential theft or broad agent-control mutation. It warrants a warning rather than a block under the stated lifecycle policy. - **Files touched:** ~/.hum/engine, ~/.hum/engine-install.json, ~/.hum/update.json, ~/.hum/update.log - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh, https://metaphi.ai/hum ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package registers an automatic postinstall hook., The postinstall hook imports and invokes the engine installer when the bundled engine version is absent., The installer downloads and executes Astral's uv installer through a shell, then installs a Python engine package., The CLI can later launch detached background updates that execute a remotely fetched installer script. - **Evidence against:** The inspected JavaScript has no browser credential collection or secret exfiltration logic., The frontend network socket is restricted to 127.0.0.1 for its local engine., The installation target is the package's own .hum directory rather than a broad agent configuration surface. ## Affected versions and remediation This report applies to @metaphi-ai/hum@0.1.63. - Review the evidence and your use of @metaphi-ai/hum@0.1.63 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
