What it looks for

its detection, as SigmaHQ writes it

detection:
  filter_1:
    CommandLine|contains:
      - 'hklm'
      - 'hkey_local_machine'
  filter_2:
    CommandLine|endswith:
      - '\system'
      - '\sam'
      - '\security'
  selection_cli:
    CommandLine|contains|windash: ' -E '
  selection_img:
    - Image|endswith: '\regedit.exe'
    - OriginalFileName: 'REGEDIT.EXE'
  condition: all of selection_* and not all of filter_*

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 Oddvar Moe, Sander Wiebing, oscd.community, 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.

Command lines that trip it

everyday examples from tldr-pages, CC BY 4.0, each read by CmdID

Export a specific registry key and contents to a file on the page for regedit.exe

The commands LOLBAS or GTFOBins documents for regedit.exe trip it too: each is on its program’s page, read by CmdID.
