Correlates the use of Impacket scripts (wmiexec.py or smbexec.py compiled variants) executing remote commands via WMI or SMB services on target endpoints. Specifically looks for 'wmiprvse.exe' or 'services.exe' initiating 'cmd.exe' or 'powershell.exe' with command-line arguments indicating local host or administrative share access and redirection to a temporary directory.
