What it detects

This rule detects the command redirection pattern produced by Impacket wmiexec where cmd.exe is spawned by WmiPrvSE.exe to run a command and write output to a local admin share path. This semi interactive execution over WMI is a hallmark of lateral movement using stolen credentials as seen in the UAT-5918 activity.
