## Config This is meant to run only on datasources using Windows security event 4688 that captures the process clone creation. 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.
process where event.code:"4688" and process.executable : "?:\\Windows\\System32\\lsass.exe" and process.parent.executable : "?:\\Windows\\System32\\lsass.exe"
