Identifies AWS IoT Secure Tunneling localproxy started in destination mode that then resolves and connects to the Secure Tunneling data plane, data.tunneling.iot..amazonaws.com, on TCP/443. Destination mode opens no listener; once the operator joins the tunnel the proxy forwards streams to a local service such as SSH on 127.0.0.1:22. Public red-team research shows this signed, documented binary used as post-exploitation C2 that resembles legitimate IoT device management. OpenTunnel and access tokens live in the operator's AWS account, not the victim's.
