Adversaries may stop or disable services on a system to render those services unavailable to legitimate users. Stopping critical services can inhibit or stop response to an incident or aid in the adversary's overall objectives to cause damage to the environment.  Services may not allow for modification of their data stores while running. Adversaries may stop services in order to conduct Data Destruction. 
Before encrypting the process, EKANS first kills the process if its name matches one of the processes defined on the kill-list.   EKANS also utilizes netsh commands to implement firewall rules that blocks any remote communication with the device. 
Segment operational network and systems to restrict access to critical system functions to predetermined management systems.
