Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 18 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Staged Payload Carrier - **Selected version:** 0.1.9 - **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. The package has a concrete unverified remote-binary delivery path at install time and execution path at command invocation. That is unsafe and unresolved, but the available source does not prove malicious intent or a completed malicious action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-01T07:51:34.389Z - **Finished:** 2026-09-01T07:53:04.148Z - **Download time:** 4318 ms - **Static scan time:** 339 ms - **AI review time:** 85100 ms - **Total time:** 89759 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:** Installation downloads an unverified native executable from a mutable release URL. The launcher can execute that downloaded file when the user runs emp. - **Trigger:** npm installation triggers postinstall; running emp triggers the launcher fallback. - **Impact:** A changed release asset or overridden download URL can cause unreviewed native code to run. - **Evidence paths:** package.json, scripts/postinstall.js, bin/emp.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T07:53:04.148Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native payload download followed by local execution. - **Rationale:** The package has a concrete unverified remote-binary delivery path at install time and execution path at command invocation. That is unsafe and unresolved, but the available source does not prove malicious intent or a completed malicious action. - **Files touched:** scripts/postinstall.js, bin/emp.js, dist/emp-win.exe, dist/emp-macos, dist/emp-linux - **Network endpoints:** https://github.com/saintdevzz/emp-cli/releases/latest/download/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The install lifecycle automatically downloads a platform executable from a mutable GitHub latest-release URL., The downloaded bytes are written as an executable without a hash or signature check., Running the emp command can download the same remote executable and spawn it. - **Evidence against:** The installer writes only the package's dist directory and does not modify agent configuration or unrelated project files., The inspected JavaScript does not harvest credentials or send local data elsewhere., The only hard-coded download host is the package repository's GitHub host. ## Affected versions and remediation This report applies to emp-code@0.1.9. - Review the evidence and your use of emp-code@0.1.9 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.
