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. No concealed payload, self-dependency, credential harvesting, or unpaired install-time network activity was found. However, the lifecycle hook creates persistent root services and enables automatic remote package updates, which is a concrete capability that warrants warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-12T18:28:09.316Z - **Finished:** 2026-09-12T18:29:19.299Z - **Download time:** 517 ms - **Static scan time:** 64 ms - **AI review time:** 69399 ms - **Total time:** 69983 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 global root installation automatically writes and enables persistent HYN systemd units. Those units can check the npm registry and install later package releases; portal pairing enables periodic telemetry and portal-directed update handling. - **Trigger:** Run npm install -g hyn-view as root on a Linux system with systemd. - **Impact:** It establishes root-level persistence and expands trust to future registry releases; paired installations can send monitoring telemetry to the HYN endpoint. - **Evidence paths:** package.json, scripts/postinstall.sh, lib/setup.sh, lib/core.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-12T18:29:19.299Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-created persistent monitor with automatic self-update. - **Rationale:** No concealed payload, self-dependency, credential harvesting, or unpaired install-time network activity was found. However, the lifecycle hook creates persistent root services and enables automatic remote package updates, which is a concrete capability that warrants warning. - **Files touched:** /etc/hyn-view/config, /etc/hyn-view/secrets, /var/lib/hyn-view, /etc/systemd/system/hyn-\*.service, /etc/systemd/system/hyn-\*.timer, /usr/local/bin/hyn - **Network endpoints:** https://registry.npmjs.org, https://www.hyn-view.in/api/agent/v1, https://hyn-view.in/api/agent/v1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook invokes unattended setup on global root Linux installs., Setup creates and enables persistent systemd services and timers., The resident service has full filesystem write access and self-update capability., The default configuration enables automatic updates from the npm registry. - **Evidence against:** The hook exits for local installs, non-Linux hosts, non-root users, and systems without systemd., No runtime dependency or self-dependency is declared., Cloud upload requires a separately paired node token; no endpoint is contacted by postinstall itself., Flagged test scripts are readable shell regression tests using temporary directories, not hidden payloads. ## Affected versions and remediation This report applies to hyn-view@1.10.0. - Review the evidence and your use of hyn-view@1.10.0 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.

Public source snippet (untrusted): ```text # What the managed units are allowed to do, and what they are held back from. # # hyn has FULL WRITE ACCESS to the filesystem. That is deliberate and it is a # reversal: these units used to run under ProtectSystem=strict with # ReadWritePaths limited to one state directory, which read well in a README and # in practice meant the agent could not install its own updates, could not # rewrite its own units, and could not repair itself -- every one of those needs # /usr and /etc. A monitor that cannot fix itself on an unattended box is worse ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** hyn-view - **Ecosystem:** npm - **Version:** 1.10.0 - **License:** MIT - **Version published:** 2026-09-12T18:27:10.083Z - **Package first seen:** 2026-08-06T21:29:43.148Z - **Package last seen:** 2026-10-15T17:28:03.231Z - **Known versions:** 11 - **Latest version:** 2.1.0 - **Appeal under review:** No - **Description:** Network-first, ultra-low-overhead terminal system monitor for Ubuntu Server.
