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