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 embedded source suggests a credential handoff, but the hash-verified executable analysis is limited to bounded source candidates and does not prove reachability or rule out other native behavior. Manual review is needed before classifying the package as malicious or clean. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-21T10:46:41.522Z - **Finished:** 2026-10-21T10:48:11.736Z - **Download time:** 7057 ms - **Static scan time:** 616 ms - **AI review time:** 82540 ms - **Total time:** 90214 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:** Recovered executable code suggests a default-enabled handoff of local provider access tokens to a local-subscription API. The bounded analysis does not establish that this code is reachable in the shipped executable, so no attack is confirmed. - **Trigger:** A worker starts with local logins enabled; recovered configuration defaults this option to enabled. - **Impact:** If reachable, this could expose third-party access tokens to the service API; actual execution and recipient remain unresolved. - **Evidence paths:** .lpm-inspection-Ltenil/0-73766fdb302b.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-21T10:48:11.736Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The recovered code collects provider token records and passes them to a request for the local-subscription route. - **Rationale:** The embedded source suggests a credential handoff, but the hash-verified executable analysis is limited to bounded source candidates and does not prove reachability or rule out other native behavior. Manual review is needed before classifying the package as malicious or clean. ### Review decision - **Verdict:** Manual Review - **Confidence:** 83.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies a Darwin ARM64 native CLI package and contains no lifecycle hooks or JavaScript entrypoint., Recovered executable source extracts provider OAuth access tokens and passes provider records to a local-subscription request from a worker helper when local logins are enabled., The recovered configuration defaults local logins to enabled; its help text says Reason receives current login access tokens., The offline analysis contains only bounded embedded-source windows and says they do not establish loader reachability or rule out other native behavior. - **Evidence against:** The manifest has no install-time script, and the recovered help text discloses the local-login feature and says refresh tokens are not sent. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.503. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.503 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.
