This time we are going to focus on fuzzing frameworks, so let’s start by looking at how the general logical structure of a fuzzer is, although not all follow the same model, we can distinguish the following generic components:

Fuzzing is a dynamic technique used extensively (especially in recent years) to discover bugs in software that, with a little (bad) luck, could lead to security vulnerabilities. The main idea behind fuzzing is to provide invalid or malformed data as input to a system in order to trigger unexpected behavior such as a crash.
