Suspicious Keyboard Layout Load via Registry
This rule detects the installation or modification of keyboard preload settings in the Windows Registry, specifically looking for suspicious keyboard layouts such as Persian (Iran) or Vietnamese. This activity is considered suspicious in environments where such layouts are not expected, particularly in systems maintained by US staff. The detection focuses on changes to the 'Keyboard Layout\Preload' and 'Keyboard Layout\Substitutes' registry keys.
