T1529 - System Shutdown/Reboot

Description from ATT&CK

Adversaries may shutdown/reboot systems to interrupt access to, or aid in the destruction of, those systems. Operating systems may contain commands to initiate a shutdown/reboot of a machine. In some cases, these commands may also be used to initiate a shutdown/reboot of a remote computer.(Citation: Microsoft Shutdown Oct 2017) Shutting down or rebooting systems may disrupt access to computer resources for legitimate users.

Adversaries may attempt to shutdown/reboot a system after impacting it in other ways, such as Disk Structure Wipe or Inhibit System Recovery, to hasten the intended effects on system availability.(Citation: Talos Nyetya June 2017)(Citation: Talos Olympic Destroyer 2018)
