Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.7.1 - **Selected version is latest:** Yes - **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. The code establishes an automatic remote-binary and first-party agent-extension lifecycle, but does not show theft, destructive action, stealth persistence, or a self-dependency chain. This is a guarded lifecycle risk rather than proven malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-04T03:42:59.449Z - **Finished:** 2026-09-04T03:44:39.494Z - **Download time:** 516 ms - **Static scan time:** 104 ms - **AI review time:** 99425 ms - **Total time:** 100045 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:** Installing the package automatically downloads a platform binary and adds a Tier0 agent skill globally. This is a package-owned extension setup, but it changes an agent control surface without an explicit install command. - **Trigger:** npm postinstall, or invoking the CLI when its managed binary is absent - **Impact:** A released remote binary runs locally and can create the Tier0 agent extension. - **Evidence paths:** package.json, lib/install.js, bin/tier0.js, lib/uninstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T03:44:39.494Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** native binary download followed by global agent-skill installation - **Rationale:** The code establishes an automatic remote-binary and first-party agent-extension lifecycle, but does not show theft, destructive action, stealth persistence, or a self-dependency chain. This is a guarded lifecycle risk rather than proven malware. - **Files touched:** ~/.tier0/bin/tier0, ~/.tier0/bin/.version, ~/.tier0/skills, ~/.agents/skills/tier0 - **Network endpoints:** github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook automatically runs the downloader., The installer downloads and executes a released native binary, then globally installs an agent skill., The CLI invokes installation when the managed binary is absent. - **Evidence against:** The downloaded archive is checked against a SHA-256 checksum before extraction., No source code reads or transmits credentials, environment values, or arbitrary user files., The uninstall hook removes agent skills only when the user supplies --remove-skills. ## Affected versions and remediation This report applies to @tier0/cli@0.7.1. - Review the evidence and your use of @tier0/cli@0.7.1 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.
