What it detects

This rule flags Windows command-line activity that adds printer ports via Add-PrinterPort -Name when the command line includes executable, DLL, or batch file extensions. It also matches printer port creation commands containing the string "Generic / Text Only." These behaviors can matter because attackers may abuse printer port configuration to trigger execution or persistence using crafted targets. The detection relies on process creation telemetry and string matching on the process command line.
