@reason-machines/cli-win32-arm64@0.2.432
Reason CLI native binary for win32-arm64
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe embedded executable source shows default-enabled forwarding of saved third-party AI access tokens to a service API. This is a concrete credential exposure risk, but the inspected evidence does not establish malicious use, so warn rather than block.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Starting the Reason worker with localLogins enabled; the setting defaults to enabled when omitted.
Impact
The service may receive access tokens for third-party AI accounts; the inspected source does not establish subsequent misuse.
Mechanism
The executable scans local authentication stores, selects provider access tokens, and submits provider, access-token, and expiry data to the service's local-subscription route.
AI rationale
The embedded executable source shows default-enabled forwarding of saved third-party AI access tokens to a service API. This is a concrete credential exposure risk, but the inspected evidence does not establish malicious use, so warn rather than block.
Evidence
.lpm-inspection-B4IM25/0-e3f262ab526d.txtbin/reason.exe
Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The executable source reads saved AI-tool authentication data and extracts access tokens; the handoff retains access tokens but omits refresh tokens.
- Worker startup invokes the handoff when localLogins is enabled, and that setting defaults to true when omitted.
- The handoff submits token data through the device-authenticated local-subscription API route.
- At the flagged agent-configuration location, the sandbox runtime lists .mcp.json among names it handles; the excerpt shows no configuration write.
- The offline executable analysis contains bounded embedded source candidates and warns that they do not establish loader reachability.
