 5    Detects the attempt to create an ActiveScriptEventConsumer via WMIC.EXE.
 6    An ActiveScriptEventConsumer is a built-in Windows Management Instrumentation (WMI) class that
 7    automatically executes a predefined script (in VBScript or JScript) whenever a specific system event occurs.
 8    Adversaries often abuse ActiveScriptEventConsumer to maintain persistence on a compromised host by executing a malicious script whenever a specific event occurs.
