Securi-Tay 2017 - A Window into Ring0
With the rise of sandboxes and locked down user accounts attackers are increasingly resorting to attacking kernel mode code to gain full access to compromised systems. This talk aims to provide an overview of the Windows kernel mode attack surface and how to interact with it. This talk will demonstrate the tools available for finding bugs in Windows kernel mode code and drivers together with highlighting some of the lower hanging fruit, common mistakes and the steps being taken (or lack of steps being taken) to mitigate the risks posed. The talk will then cover common exploitation techniques to gather information about the state of kernel mode memory and to gain code execution as SYSTEM using examples from publicly known exploits.
