Cobalt Strike Beacon Object File (BOF) that uses WinStationConnect API to perform local/remote RDP session hijacking. With a valid access token / kerberos ticket (e.g., golden ticket) of the session owner, you will be able to hijack the session remotely without dropping any beacon/tool on the target server.
To enumerate sessions locally/remotely, you could use Quser-BOF.
