Description

Adversaries may seek to achieve a sustained loss of control or a runaway condition in which operators cannot issue any commands even if the malicious interference has subsided.123

Procedure Examples

Industroyer's data wiper component removes the registry "image path" throughout the system and overwrites all files, rendering the system unusable.4
Some of Norsk Hydro's production systems were impacted by a LockerGoga infection. This resulted in a loss of control which forced the company to switch to manual operations.56
