Penetration Testing: A Survival Guide

Types of fuzzing techniques

Fuzzing can be broadly categorized as smart and dumb fuzzing. In technical terms, it is known as Mutation fuzzing and Generation fuzzing. Providing random data as input is what fuzzing is all about. The input can be entirely random with no relation and knowledge about what the desired input should look like, or the input can be generated emulating valid input data with some alteration (hence the name generation fuzzing).

Mutation fuzzing

Mutation fuzzing, or Dumb fuzzing, employs a faster approach using sample data, but it lacks understanding of the format and structure of the desired input. Using Mutation fuzzing, you can create your fuzzer without much effort. The Mutation fuzzing technique uses a sample input and mutates ...
