NewActiveScriptEventConsumer Creation Attempt via Wmic.EXE — Sigma Rule
Sigma rule ebef4391-1a81-4761-a40a-1db446c0e625. NewActiveScriptEventConsumer Creation Attempt via Wmic.EXE — Sigma Rule. 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.

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.
