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 inspected artifact contains a potentially sensitive credential-transfer path, but its bounded embedded-source analysis cannot establish that the path executes. This unresolved native behavior warrants manual review rather than a confirmed attack verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-21T08:19:39.477Z - **Finished:** 2026-10-21T08:22:01.501Z - **Download time:** 11114 ms - **Static scan time:** 630 ms - **AI review time:** 130279 ms - **Total time:** 142024 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:** The native executable's bounded embedded-source analysis contains code that appears to collect third-party AI login tokens and submit them to a Reason local-subscription API. The analysis does not establish that this code is loaded or executed, so no active attack is confirmed. - **Trigger:** The candidate handoff is associated with worker startup when local logins are enabled; executable reachability is unresolved. - **Impact:** If reachable, the code could disclose current third-party access tokens to the Reason service; an active transfer is unverified. - **Evidence paths:** bin/reason.exe, .lpm-inspection-G0pBzh/0-b5535274c9cd.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-21T08:22:01.501Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Candidate code reads OAuth token records and submits changed records to the local-subscription route through the Reason device client. - **Rationale:** The inspected artifact contains a potentially sensitive credential-transfer path, but its bounded embedded-source analysis cannot establish that the path executes. This unresolved native behavior warrants manual review rather than a confirmed attack verdict. - **Files touched:** bin/reason.exe - **Network endpoints:** /app/local-runtime/local-subscription ### Review decision - **Verdict:** Manual Review - **Confidence:** 93.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** Embedded code appears to parse OAuth access tokens from local provider stores into provider records., A background routine submits changed records to a local-subscription API route through the Reason device client when local logins are enabled., The connect path defaults local logins on without an override or API key; embedded help says Reason receives current access tokens., The trusted analysis says these embedded source windows do not prove loader or bytecode reachability, leaving activation and actual sends unresolved. - **Evidence against:** Embedded help describes local-login sharing and says only current access tokens are used; that disclosure does not establish whether the candidate code runs or resolve recipient consent. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-x64@0.2.499. - Review the evidence and your use of @reason-machines/cli-win32-x64@0.2.499 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.
