Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 10 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Unknown - **Selected version:** 1.0.5 - **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 shipped entrypoint is substantially obfuscated and includes HTTP/HTTPS imports alongside verification and security exports, leaving runtime behavior unresolved. The manifest shows no install-time hook, and the inspected excerpts do not establish a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-26T08:31:22.505Z - **Finished:** 2026-10-26T08:32:13.159Z - **Download time:** 505 ms - **Static scan time:** 245 ms - **AI review time:** 49903 ms - **Total time:** 50654 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:** No concrete attack was established, but the obfuscated runtime prevents reliable assessment of its network behavior and exported security functions. - **Trigger:** Importing the package or calling its exported functions. - **Impact:** Unresolved risk that runtime network behavior could exceed the stated security purpose. - **Evidence paths:** lib/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-26T08:32:13.159Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A large obfuscated entrypoint imports HTTP and HTTPS modules and constructs verification-related values through hidden calls; the inspected source did not establish the requests’ destinations or payloads. - **Rationale:** The shipped entrypoint is substantially obfuscated and includes HTTP/HTTPS imports alongside verification and security exports, leaving runtime behavior unresolved. The manifest shows no install-time hook, and the inspected excerpts do not establish a concrete attack. - **Files touched:** lib/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 76.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package entrypoint is a 278 KB single-line obfuscated module that imports Node HTTP and HTTPS modules., The entrypoint exports update-check and security-middleware functions, but their behavior is obscured., The entrypoint initializes verification state and builds IP source values through obfuscated calls. - **Evidence against:** The manifest has no install, preinstall, or postinstall hook; its prepublishOnly hook runs the build script., The package describes itself as a license and environment security core, consistent with its verification and middleware exports. ## Affected versions and remediation This report applies to zireku-ls@1.0.5. - Review the evidence and your use of zireku-ls@1.0.5 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.
