An individual reading this should have a solid understanding of ASM, how computers handle memory, the Win32 Debugging API, and at least some knowledge of Windows internals. This code most likely will not work on any *nix platform due to the fundamental differences of the Operating Systems. Any other knowledge in the field of reverse engineering is also a plus. One great thing about learning and implementing anti-debugging is that you also develop your reversing skills, which is a great plus to anyone interested in the field. Along with the other mentioned subjects, an interested reader should also be familiar with the tools used for binary application reversing such as OllyDBG, WinDBG, SoftICE, IDA Pro, and others.
