I need to create a report that alerts on the following:

I'd like to know when and by who added a specific group to a user in AD.

Any insight or help is greatly appreciated.

Hi @itsmevic,
the search could be something like this:

index=wineventlog (EventCode=4728 OR EventCode=4756)
| table _time Account_name EventCode EventDescription

please check the Account_name field, it could be different (e.g. user)

Ciao.
