Detects instances where the Windows Management Instrumentation service (WmiPrvSE.exe) spawns a command shell (cmd.exe) with command-line arguments involving standard output redirection (2>&1), often used to capture error and output streams in remote command execution scenarios. This pattern is commonly observed during lateral movement or remote administration activity.
