We're pleased to announce that James Loureiro and Georgi Geshev will be presenting on kernel fuzzing at DEF CON 24 in Las Vegas.

Event Description

DEF CON has been a part of the hacker community for over two decades. Originally started in 1993, it was a meant to be a party for members of "Platinum Net", a Fido protocol based hacking network out of Canada. DEF CON has now become one of the oldest continuously running hacker conventions around, and also one of the largest.

Talk presented by MWR

  • Time: 15:00:00
  • Room: Track Three
  • Topic: Platform Agnostic Kernel Fuzzing
  • Speakers: James Loureiro and Georgi Geshev
  • Description: A number of toolsets have been around for a while which propose methods for identifying vulnerabilities in kernels, in particular POSIX kernels. However, none of these identified a method for generic fuzzing across Windows and POSIX kernels and have not been updated for some time.

    This presentation will outline the research which has occurred in order to find exploitable bugs across both Windows and POSIX kernels, focusing on fuzzing system calls and library calls in the Windows environment. System calls will be briefly explained, how they work and how these can be fuzzed in order to find bugs. The presentation will then move on to explaining core libraries in the Windows environment and how to fuzz these effectively.

    Other issues with creating a kernel fuzzing environment will be discussed, such as effective logging of calls in which the machine could BSOD and kernel panic, and how to correctly reproduce vulnerabilities that have been identified by the fuzzer. We will also cover efficient scaling of a kernel fuzzer so that a number of virtual machines are in operation that can generate a large number of crashes.

    Finally, a brief summary of the vulnerabilities that have been identified will be provided.
