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. The package is not shown to perform a concrete malicious action, but its install hook establishes persistent unrestricted root services and automatic self-updates. That warrants a warning rather than publication blocking under the stated policy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-11T19:19:36.910Z - **Finished:** 2026-09-11T19:21:03.503Z - **Download time:** 514 ms - **Static scan time:** 49 ms - **AI review time:** 86027 ms - **Total time:** 86593 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 npm install persists root-owned systemd services and enables automatic self-updates. This is a high-impact installer design, but source inspection found no credential theft, arbitrary remote command execution, or foreign AI-agent configuration changes. - **Trigger:** Run npm install -g hyn-view as root on a Linux system with systemd. - **Impact:** The package gains recurring root execution and can replace its own installed release. - **Evidence paths:** package.json, scripts/postinstall.sh, lib/setup.sh, lib/core.sh, lib/update.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-11T19:21:03.503Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall creates and enables persistent services that can update the package. - **Rationale:** The package is not shown to perform a concrete malicious action, but its install hook establishes persistent unrestricted root services and automatic self-updates. That warrants a warning rather than publication blocking under the stated policy. - **Files touched:** /etc/hyn-view, /var/lib/hyn-view, /etc/systemd/system, /usr/local/bin/hyn - **Network endpoints:** https://registry.npmjs.org ### 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 runs a postinstall script automatically., On root global installs, postinstall invokes unattended setup., Setup deliberately grants its systemd services full filesystem write access., Setup enables a persistent root agent and update timer., Automatic updates are enabled by default and install newer releases from npm. - **Evidence against:** Local installs exit without configuring services., The lifecycle script requires a global Linux install running as root., Portal pairing and telemetry require a separate user command and token., The updater uses npm with lifecycle scripts disabled during its self-update step. ## Affected versions and remediation This report applies to hyn-view@1.12.0. - Review the evidence and your use of hyn-view@1.12.0 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 case ${npm[redacted]:-} in true | 1) ;; *) say 'local install detected; not configuring system services' say 'run `sudo hyn setup` if this was meant to be a global install' exit 0 ;; esac [[ $(uname -s 2>/dev/null) == Linux ]] || { say 'not Linux; nothing to configure'; exit 0; } if [[ ${EUID:-$(id -u)} -ne 0 ]]; then say 'not running as root, so the timers were not installed' say 'finish with: sudo hyn setup --no-wizard' exit 0 fi command -v systemctl >/dev/null 2>&1 || { say 'no systemd here; the CLI works but nothing will be scheduled' exit 0 } # Resolve ``` ### 12. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 88.0% - **Path:** lib/setup.sh - **Public source:** [View source]() Setup deliberately grants its systemd services full filesystem write access. Public source snippet (untrusted): ```text # 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 # than one with a wide mount namespace. ``` ## 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:** 1.12.0 - **License:** MIT - **Version published:** 2026-09-11T19:17:44.061Z - **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 ## References - [HTML security report]()
