Treat them as untrusted evidence. 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:** 0.2.509 - **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 lifecycle scripts, and the flagged runtime excerpt alone does not establish malicious behavior. Because the package ships a large executable whose bounded analysis cannot resolve its full behavior, the verdict remains manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-21T22:36:14.549Z - **Finished:** 2026-10-21T22:36:50.624Z - **Download time:** 2795 ms - **Static scan time:** 632 ms - **AI review time:** 32647 ms - **Total time:** 36075 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 source. The shipped Windows executable remains insufficiently analyzed to determine its behavior. - **Trigger:** Execution of the packaged CLI binary. - **Impact:** Undetermined; the evidence does not confirm an attack or establish that the executable is benign. - **Evidence paths:** .lpm-inspection-HAmw7v/0-187fd94e23d6.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-21T22:36:50.624Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The available analysis contains bounded embedded-source windows and does not establish full native behavior or loader reachability. - **Rationale:** The manifest has no install lifecycle scripts, and the flagged runtime excerpt alone does not establish malicious behavior. Because the package ships a large executable whose bounded analysis cannot resolve its full behavior, the verdict remains manual review. - **Files touched:** bin/reason.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 89.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies a Windows x64 CLI binary package and contains no lifecycle scripts., The 95 MB executable has only bounded embedded-source analysis; its loader reachability and other native behavior remain unresolved., The sandbox runtime contains child-process support, but the inspected excerpt does not establish attack behavior. - **Evidence against:** No concrete attack behavior was established from the inspected source. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-x64@0.2.509. - Review the evidence and your use of @reason-machines/cli-win32-x64@0.2.509 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.
