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
file where event.type in ("creation", "change") and
 /* via RDP TSClient mounted share or SMB */
  (process.name : "mstsc.exe" or process.pid == 4) and
   file.path : "C:\\*\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\*"

Framework: MITRE ATT&CKTM
