Investigation guide

edit
## Setup

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.parent.name : "java" and
  process.name : ("sh", "bash", "dash", "ksh", "tcsh", "zsh", "curl", "wget")

Framework: MITRE ATT&CKTM
