About: Weird machine

The concept of weird machine is a theoretical framework to understand the existence of exploits for security vulnerabilities. Exploits exist empirically, but were not studied from a theoretical perspective prior to the emergence of the framework of weird machines. In computer security, the weird machine is a computational artifact where additional code execution can happen outside the original specification of the program. It is closely related to the concept of weird instructions, which are the building blocks of an exploit based on crafted input data.
