Hi @Parmar, thanks for reaching us using the Live Community.

As you can see in our documentation, the Event IDs that are captured by the XDR agent and that can work for your request are this:

4720: A user account was created
4722: A user account was enabled
4725: A user account was disabled
4726: A user account was deleted
4727, 4731, 4754: Creation of Groups
4728, 4732, 4756: Group member additions
4729, 4733, 4757: Group member removals

With this on mind, you could be able to create a XQL Query to use it as a correlation rule like this one for "Group Creation":

dataset = xdr_data | filter agent_hostname = "YOUR_DC_NAMES" //Set your Domain Controller names with and 'or' statement using the agent_hostname field | filter event_id in ("4727","4731","4754") //Set the EventID values to the required correlation rule, in this example only for Group Creations

With the result data, you can apply the filters on the fields (using the field stage) to only have the information you require.

If this post answers your question, please mark it as the solution.
