Detects memory regions associated with 'ntdll.dll' that are marked with Read, Write, and Execute (RWX) permissions. This pattern is commonly used in process injection techniques, such as reflective DLL injection or shellcode execution, where adversaries prepare executable memory space within a legitimate process to bypass standard security controls.
