Service Stop

Service Stop
Technique
ID	T881
Tactic	Impair Process Control
Data Sources	Process command-line parameters, Process monitoring, Windows Registry, API monitoring
Asset	Human-Machine Interface, Control Server, Data Historian, Engineering Workstation

Description

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.1

Services may not allow for modification of their data stores while running. Adversaries may stop services in order to conduct Data Destruction.1

Procedure Examples

Industroyer has the capability to stop a service itself, or to login as a user and stop a service as that user.2
KillDisk looks for and terminates two non-standard processes, one of which is an ICS application.3
