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 Ialle Teixeira @teixeira0xfffff, Austin Songer @austinsonger, 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.

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