Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 0.2.390 - **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The manifest and inspected excerpts do not establish malicious behavior, and the credential handover appears within a local-login feature. The primary executable analysis is explicitly bounded, leaving material behavior unresolved; manual review is appropriate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 80.0% - **Started:** 2026-10-18T09:31:54.789Z - **Finished:** 2026-10-18T09:33:53.515Z - **Download time:** 3047 ms - **Static scan time:** 595 ms - **AI review time:** 115083 ms - **Total time:** 118726 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 attack was identified from the inspected excerpts. The primary executable’s bounded source analysis leaves its full behavior unresolved. - **Trigger:** Running the bundled native CLI or its worker; complete activation could not be verified from the available analysis. - **Impact:** An attack impact could not be established; the incomplete primary-executable analysis prevents resolving whether additional behavior exists. - **Evidence paths:** .lpm-inspection-3frWEh/0-3ea84b9d27d6.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T09:33:53.515Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The analyzed code includes local coding-agent credential collection and a setting-gated handover flow, but the available excerpts do not establish the full executable call chain or recipient behavior. - **Rationale:** The manifest and inspected excerpts do not establish malicious behavior, and the credential handover appears within a local-login feature. The primary executable analysis is explicitly bounded, leaving material behavior unresolved; manual review is appropriate. ### Review decision - **Verdict:** Manual Review - **Confidence:** 80.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies a Windows ARM64 native-binary package; the inspected manifest excerpt shows no JavaScript entry point., The bundled runtime contains code that reads credentials from local coding-agent stores and hands them to a local-login flow when enabled., The offline executable analysis is explicitly bounded and cannot establish loader reachability or rule out other native behavior., The indicated runtime location filters paths and names agent command and agent directories; that excerpt alone does not establish a configuration change. - **Evidence against:** The inspected manifest excerpt contains package metadata and bundled-file declarations, with no lifecycle script shown., The inspected excerpts do not establish an unrelated credential recipient or a concrete attack. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-arm64@0.2.390. - Review the evidence and your use of @reason-machines/cli-win32-arm64@0.2.390 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.
