What it detects

This rule detects the Impacket wmiexec pattern where a command is executed through WMI and its output is redirected to the local ADMIN$ share on 127.0.0.1. The BlackJack group used WMIExec for remote command execution during lateral movement, and this loopback ADMIN$ redirection is characteristic of the tool.
