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:** 0.2.393 - **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 has no install hook, and the inspected agent-configuration location does not establish a write. The 107 MB native CLI remains materially unresolved because its bounded analysis cannot establish full behavior, so manual review is appropriate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-18T10:28:41.833Z - **Finished:** 2026-10-18T10:32:06.015Z - **Download time:** 117715 ms - **Static scan time:** 602 ms - **AI review time:** 85864 ms - **Total time:** 204182 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 is confirmed. The packaged native CLI remains unresolved because its available offline analysis covers only bounded embedded source windows. - **Trigger:** Potentially running bin/reason.exe; its relevant behavior was not fully established by the inspected analysis. - **Impact:** No concrete effect is established; the executable's behavior remains unknown. - **Evidence paths:** bin/reason.exe, .lpm-inspection-RWS6lW/0-27ffab25b3de.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T10:32:06.015Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The analysis does not establish embedded-source reachability or rule out other native behavior. - **Rationale:** The manifest has no install hook, and the inspected agent-configuration location does not establish a write. The 107 MB native CLI remains materially unresolved because its bounded analysis cannot establish full behavior, so manual review is appropriate. ### Review decision - **Verdict:** Manual Review - **Confidence:** 84.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json contains package metadata only; it declares no lifecycle scripts or entrypoints., At the flagged source location, the bundle lists .mcp.json among paths but this excerpt does not show a configuration write or caller., Offline analysis of bin/reason.exe covers bounded embedded source windows and says it cannot establish loader reachability or rule out other native behavior. - **Evidence against:** The manifest shows no npm lifecycle hook that would run during installation. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-x64@0.2.393. - Review the evidence and your use of @reason-machines/cli-win32-x64@0.2.393 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.
