The reviewed frontend later launches that external engine; no package-side credential exfiltration was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 95.0% - **Started:** 2026-08-25T02:04:54.021Z - **Finished:** 2026-08-25T02:05:34.392Z - **Download time:** 766 ms - **Static scan time:** 7559 ms - **AI review time:** 32045 ms - **Total time:** 40371 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation can download and execute a remote uv installer, then install a separate hum-cli engine. The reviewed frontend later launches that external engine; no package-side credential exfiltration was confirmed. - **Trigger:** npm postinstall when hum-engine and uv are absent - **Impact:** Unconsented execution of remotely supplied installer code and installation of an unreviewed engine in the user environment. - **Evidence paths:** package.json, scripts/postinstall.js, bin/hum.js, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-25T02:05:34.392Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote bootstrap execution and persistent external CLI installation - **Rationale:** The package contains a high-risk postinstall bootstrap that executes remote code and installs an external engine without user confirmation. It is suspicious installer abuse, but source inspection does not establish malicious theft, destruction, or AI-agent hijacking. - **Files touched:** scripts/postinstall.js, ~/.local/bin, dist/cli.mjs - **Network endpoints:** https://astral.sh/uv/install.ps1, https://astral.sh/uv/install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall automatically installs missing tooling and an external hum-cli engine., On Unix it downloads a remote installer and pipes it directly to sh., On Windows it downloads a remote PowerShell script and executes it with ExecutionPolicy ByPass., The installed engine is launched later and receives user-entered shell commands. - **Evidence against:** The reviewed JS CLI connects only to 127.0.0.1 for its engine protocol., Shell commands require an explicit ! user input prefix., No credential harvesting or package-side exfiltration was confirmed in inspected source. ## Public findings ### 1.
