This session will look at a critical flaw in the design of Windows Kernel Patch Protection (PatchGuard), a system used to prevent modification to kernel code and other critical structure. The design of PatchGuard will be discussed, along with the design of an attack which uses the flaw in PatchGuard to disable the PatchGuard response entirely. In the end, a set of mitigations will be proposed.
