Kernel rootkit, that lives inside the Windows registry value data.

Rootkit uses the zero day vulnerability in win32k.sys (buffer overflow in function win32k!bInitializeEUDC()) to get the execution at the OS startup.
Features:
-
NDIS-based network backdoor (+ meterpreter/bind_tcp).
-
In order to avoid unknown executable code detection it moves itself in the memory over discardable sections of some default Windows drivers.
-
Completely undetectable by public anti-rootkit tools.
-
Working on Windows 7 (SP0, SP1) x86.
This rootkit was originally presented at the ZeroNights 2012 conference during my talk.
