Hey friends!
So the requirement is to create a detection rule that enriches all domains except for what's added in the reference list which usually have all my internal domains. I know we do $field in %<reference list>, how would I instruct "Only enrich domains which are given in the reference list.
This doesn't seem to work:
$e1.principal.administrative_domain = $dom
$dom not in %<reference_list_name>?
