What it looks for

its detection, as SigmaHQ writes it
detection:
  selection_cli:
    CommandLine|contains|all:
      - '-- '
      - 'collect'
  selection_img:
    - Image|endswith: '\dotnet-trace.exe'
    - OriginalFileName: 'dotnet-trace.dll'
  condition: all of 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 Jimmy Bayne (@bohops), 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.
