Description: xkpsm.sys is an xkeeper kernel driver from JiranJikyosoft. The driver
13+
exposes IOCTL 0x8505E008 to user mode and reaches ZwTerminateProcess, enabling
14+
kernel-mediated process termination without sufficient caller or target validation.
15+
This makes the driver useful in BYOVD-style process termination and security tool
16+
impairment scenarios after it is loaded.
17+
Usecase: Terminate processes
18+
Privileges: kernel
19+
OperatingSystem: Windows 10
