Black Hat Briefings, Las Vegas 2005 [audio] Presentations From The Security Conference

Almost every possible method and technique regarding Windows exploitation has been discussed in depth. Surprisingly, a topic that has rarely been touched on publicly is the remote exploitation of Win32 kernel vulnerabilities; a number of kernel vulnerabilities have been published, yet no exploit code has surfaced in the public arena. I predict we will see more kernel vulnerabilities in the future, as more core networking components are being implemented at the driver level. In this presentation I will walk through the remote exploitation of a kernel level vulnerability. A number of payloads will be discussed and demonstrated, and I will explain how to overcome the various obstacles that arise when attempting to exploit ring 0 vulnerabilities. As a final demonstration, we will say goodnight to the Windows OS entirely. Barnaby Jack is a Senior Research Engineer at eEye Digital Security.
