Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 31 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 0.2.321 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package has no install hook, but its user-started worker defaults to forwarding discovered provider login tokens to the Reason service. Because the handoff is disclosed as a product feature yet enabled by default without a recipient-specific consent gate, warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-16T11:03:04.701Z - **Finished:** 2026-10-16T11:05:21.089Z - **Download time:** 3305 ms - **Static scan time:** 4792 ms - **AI review time:** 128290 ms - **Total time:** 136388 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:** A connected worker can send existing third-party provider login tokens to the Reason service for local-subscription checks. The handoff is enabled by default when the worker starts. - **Trigger:** The user connects a persistent worker with \`reason connect\`, then the worker starts. - **Impact:** Provider session tokens are disclosed to the Reason service, creating conditional exposure of those accounts. - **Evidence paths:** bin/vm-hands/vm-hands-entry-lite-4evh4dse.js, bin/vm-hands/vm-hands-entry-lite-t497ewn2.js, bin/vm-hands/vm-hands-entry-lite-xaq6qzmy.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T11:05:21.089Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The worker reads saved provider login data and sends each discovered login through its local-subscription request to the configured Reason API. - **Rationale:** The package has no install hook, but its user-started worker defaults to forwarding discovered provider login tokens to the Reason service. Because the handoff is disclosed as a product feature yet enabled by default without a recipient-specific consent gate, warn rather than block. - **Files touched:** bin/vm-hands/vm-hands-entry-lite-4evh4dse.js, bin/vm-hands/vm-hands-entry-lite-t497ewn2.js, bin/vm-hands/vm-hands-entry-lite-xaq6qzmy.js - **Network endpoints:** https://api.reasonmachines.ai, https://api.reasonmachines.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package manifest contains no lifecycle script., The worker reads existing Claude, Codex, and Grok login data, including access tokens., Connecting the worker enables local login handoff by default; its startup loop passes each discovered login to a local-subscription request., That request goes to the Reason API, whose production endpoint is package-aligned. - **Evidence against:** The CLI describes these logins as serving the user's Reason sessions, and the handoff is part of the user-started worker connection., The flagged agent configuration excerpts show local path handling, an explicit Playwright skill-install command, and retired MCP configuration checks; they do not establish malicious behavior. Source-similarity hints alone are not proof. ## Affected versions and remediation This report applies to @reason-machines/cli-linux-arm64@0.2.321. - Review the evidence and your use of @reason-machines/cli-linux-arm64@0.2.321 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.
