 To operate X-Agent and X-Tunnel on the DCCC and DNC networks, Unit 26165 officers set up a group of computers outside those networks to communicate with the implanted malware. The first set of GRU-controlled computers, known by the GRU as "middle servers," sent and received messages to and from malware on the DNC/DCCC networks. The middle servers, in turn, relayed messages to a second set of GRU-controlled computers, labeled internally by the GRU as an "AMS Panel." The AMS Panel served as a nerve center through which GRU officers monitored and directed the malware's operations on the DNC/DCCC networks.

The AMS Panel used to control X-Agent during the DCCC and DNC intrusions was housed on a leased computer located near Arizona.
