title: Windows OpenConsole LOLBIN Execution via Process Creation
id: fe45a3c8-cf98-4569-af75-f02788579d67
status: test
description: This rule flags process creation events where the executed binary is OpenConsole.exe, identified by the original filename or the executable path ending in \OpenConsole.exe. OpenConsole can be abused as a signed Windows utility to launch other binaries and potentially evade application allowlisting controls. The detection relies on process creation telemetry, including OriginalFileName and Image path details, while excluding the default Microsoft.WindowsTerminal app path.
