WinAuthority run requests point to an activity-reporting endpoint

Three sandbox reports show the executable sending the same application-specific request structure with different identifier-like values. A recorded HTTP 200 response in one report supports an exchange, but the evidence does not establish command and control.

The question is not simply whether the utility contacted an external server, but what that exchange reveals about the server’s role.
