Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Persistence - **Selected version:** 1.9.0 - **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 not proven malware, but automatic root-level persistence and self-updating remote maintenance create a real high-impact capability beyond a normal npm CLI. The safeguards reduce the likelihood of direct abuse but do not remove the installation-time persistence risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-11T19:29:26.712Z - **Finished:** 2026-09-11T19:31:47.200Z - **Download time:** 255 ms - **Static scan time:** 44 ms - **AI review time:** 140187 ms - **Total time:** 140488 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:** A root global installation persists a resident systemd agent and update timer. After explicit portal linking, the agent polls for update or telemetry-sync requests. - **Trigger:** Install globally as root on Linux with systemd; portal actions require a linked node token. - **Impact:** The package can keep privileged monitoring services running and can update its own installed package from the configured registry. - **Evidence paths:** package.json, scripts/postinstall.sh, lib/setup.sh, lib/cloud.sh, lib/update.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-11T19:31:47.200Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic privileged systemd persistence with constrained remote maintenance commands. - **Rationale:** This is not proven malware, but automatic root-level persistence and self-updating remote maintenance create a real high-impact capability beyond a normal npm CLI. The safeguards reduce the likelihood of direct abuse but do not remove the installation-time persistence risk. - **Files touched:** scripts/postinstall.sh, bin/hyn, lib/setup.sh, lib/cloud.sh, lib/update.sh, /etc/hyn-view, /var/lib/hyn-view, /etc/systemd/system - **Network endpoints:** https://www.hyn-view.in/api/agent/v1, https://registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The install hook runs automatically after npm installation., On root global Linux installs, the hook starts unattended system setup., Setup writes systemd units and enables a resident service plus an update timer., A linked portal can request only update or telemetry-sync actions, including a package update. - **Evidence against:** Local installs exit without changing system services., The portal path requires a stored node token and accepts only two fixed actions., The update command binds npm to the configured registry and disables lifecycle scripts., The inspected Highway and UI files contain monitoring and display code, not a hidden payload. ## Affected versions and remediation This report applies to hyn-view@1.9.0. - Review the evidence and your use of hyn-view@1.9.0 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.
