Barbervisor: Journey developing a snapshot fuzzer with Intel VT-x

By Cory Duplantis. One of the ways vulnerability researchers find bugs is with fuzzing. At a high level, fuzzing is the process of generating and mutating random inputs for a given target to crash it. In 2017, I started developing a bare metal hypervisor for the purposes of snapshot fuzzing:...
