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 Markus Neis, Florian Roth, Swachchhanda Shrawan Poudel (Nextron Systems), 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
The commands LOLBAS or GTFOBins documents for wmic.exe trip it: each is on its program’s page, read by CmdID.
