Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the npm package runs an unpinned remote bootstrap script and then installs a separate Python package automatically. This executes third-party code before the user invokes the CLI. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T10:17:29.689Z - **Finished:** 2026-09-14T10:18:25.340Z - **Download time:** 1029 ms - **Static scan time:** 4918 ms - **AI review time:** 49704 ms - **Total time:** 55651 ms The recorded confidence comes from the underlying analysis.

This executes third-party code before the user invokes the CLI. - **Trigger:** npm installation, through the postinstall lifecycle hook - **Impact:** A remote party controlling the bootstrap or Python package supply chain can execute code and modify the user's home directory during npm installation. - **Evidence paths:** scripts/postinstall.js, dist/install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-14T10:18:25.340Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote shell bootstrap followed by automatic Python package installation - **Attack narrative:** The postinstall hook invokes installCore automatically. If uv is absent, installCore runs a script fetched from astral.sh through sh or PowerShell with execution-policy bypass. It then creates ~/.hum/core and uses uv pip to download and install hum-cli, importing the result to verify it. This is an automatic remote-code bootstrap at dependency-install time, with no hash or package lock for the fetched installer or Python payload. - **Rationale:** This package performs unconsented install-time remote code execution through a curl-to-shell bootstrap and a second opaque package installation. That supply-chain execution path is sufficient to block publication. - **Files touched:** scripts/postinstall.js, dist/install.mjs, ~/.hum/core, ~/.hum/core-install.json, ~/.local/bin/uv - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The npm postinstall hook automatically imports and calls the installer., The installer downloads a remote script and pipes it directly to a shell or PowerShell with execution-policy bypass., The hook creates a home-directory virtual environment and installs the separate hum-cli Python package, whose code is then imported during installation. - **Evidence against:** The inspected installer contains no direct credential harvesting or explicit data-exfiltration logic. ## Affected versions and remediation This report applies to @metaphi-ai/hum@0.2.7. - Avoid installing @metaphi-ai/hum@0.2.7. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
