System Shutdown/Reboot (24787dca-6afd-4ab3-ab6c-32e9486ec418)
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 or network device. In some cases, these commands may also be used to initiate a shutdown/reboot of a remote computer or network device via Network Device CLI (e.g. reload).[Microsoft Shutdown Oct 2017][alert_TA18_106A]
Shutting down or rebooting systems may disrupt access to computer resources for legitimate users while also impeding incident response/recovery.
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.[Talos Nyetya June 2017][Talos Olympic Destroyer 2018]
