T1084 / ATT&CK

Windows Management Instrumentation (WMI) can be used to install event filters, providers, consumers, and bindings that execute code when a defined event occurs. Adversaries may use the capabilities of WMI to subscribe to an event and execute arbitrary code when that event occurs, providing persistence on a system. Adversaries may attempt to evade detection of this technique by compiling WMI scripts into Windows Management Object (MOF) files (.mof extension). Examples of events that may be subscribed to are the wall clock time or the computer's uptime. Several threat groups have reportedly used this technique to maintain persistence.
