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 declares no install hook, and the inspected JavaScript excerpt does not establish an attack. The primary native executable contains unresolved behavior: its bounded analysis shows credential-file-reading code candidates but cannot establish reachability or exclude other behavior, so manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-19T01:50:36.899Z - **Finished:** 2026-10-19T01:51:23.514Z - **Download time:** 6721 ms - **Static scan time:** 618 ms - **AI review time:** 39276 ms - **Total time:** 46615 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 confirmed from the inspected excerpts. The main native executable’s behavior remains materially unresolved because its bounded embedded-source analysis does not establish reachability or cover all native behavior. - **Trigger:** Execution of the packaged CLI; the relevant native code path could not be resolved from the available analysis. - **Impact:** Potential credential access cannot be assessed without resolving executable behavior; no concrete harm was established. - **Evidence paths:** .lpm-inspection-oeGnRH/0-6fd960375367.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T01:51:23.514Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The host analysis contains candidate embedded code that reads local credential files, but does not establish whether that code is active or transfers credentials. - **Rationale:** The manifest declares no install hook, and the inspected JavaScript excerpt does not establish an attack. The primary native executable contains unresolved behavior: its bounded analysis shows credential-file-reading code candidates but cannot establish reachability or exclude other behavior, so manual review is warranted. - **Files touched:** bin/reason.exe, bin/native/win32/prebuilds/win32-arm64/win32-platform.node ### Review decision - **Verdict:** Manual Review - **Confidence:** 91.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies this as a Windows ARM64 native CLI package; it declares no lifecycle hooks., The flagged runtime contains code selecting .claude/commands and .claude/agents paths, but this excerpt alone does not establish a write or its activation., The host analysis found embedded code that reads local credential files, but its bounded windows do not establish whether that code is reachable or whether credentials are sent., The 86 MB executable’s analysis explicitly cannot establish loader reachability or rule out other native behavior; the ARM64 native module was unreadable as source. - **Evidence against:** No install lifecycle hook is declared in the inspected package manifest., The inspected excerpts do not establish credential transmission or another concrete attack. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-arm64@0.2.416. - Review the evidence and your use of @reason-machines/cli-win32-arm64@0.2.416 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.
