Domain Trust Discovery Commands - Windows (Sysmon)
Adversaries may attempt to gather information on domain trust relationships that may be used to identify lateral movement opportunities in Windows multi-domain/forest environments. This use case detects executions of domain trust discovery commands used with nltest.exe. nltest.exe is not included in the detection to account for instances where nltest.exe has been renamed
