 # Vulnerable Driver Manipulation
 
 A library to manipulate drivers exposing a physical memory read/write primitive to allow the user to call any function in the kernel. There are thousands of drivers exposing physical

-but is removed after every syscall into NtShutdownSystem to prevent triggering patchguard. Although this is not patchguard friendly, using this to call a few hundred kernel functions will most likely not cause any issues. 
-This library is not ment to be used by itself, it is ment to help the programmer setup whatever they need to in the kernel (like mapping a driver or setting up paging tables).

 # Example
 
-In this example VDM syscalls into an inline hook placed on NtShutdownSystem to call memcpy exported from ntoskrnl.exe.
