What it looks for

its detection, as SigmaHQ writes it
detection:
  selection:
    CommandLine|contains: ' -i '
    Image|endswith: '/bash'
  condition: selection

The rule’s detection, its selections and fields in order of name. The whole rule, with its references and false positives, is on SigmaHQ, by @d4ns4n_, under the Detection Rule License 1.1. CmdID evaluates it on a command line alone: a test on what a command line cannot show, such as the parent process or the user, is not met.
