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
editprocess where event.type in ("start", "process_started") and process.name : "Clipup.exe" and
not process.executable : "C:\\Windows\\System32\\ClipUp.exe" and process.parent.name : "dllhost.exe" and
