Investigation guide

edit

## Config

If enabling an EQL rule on a non-elastic-agent index (such as beats) for versions <8.2, events will not define `event.ingested` and default fallback for EQL rules was not added until 8.2, so you will need to add a custom pipeline to populate `event.ingested` to @timestamp for this rule to work.

Rule query

edit

process where event.type in ("start", "process_started") and
(((process.name : "net.exe" or process.pe.original_file_name ==
"net.exe") or ((process.name : "net1.exe" or
process.pe.original_file_name == "net1.exe") and not
process.parent.name : "net.exe")) and process.args : ("group",
"user", "localgroup") and process.args : ("admin", "Domain Admins",
"Remote Desktop Users", "Enterprise Admins", "Organization
