WebA fuzzer is a program which injects automatically semi-random data into a program/stack and detect bugs. The data-generation part is made of generators, and vulnerability identification relies on debugging tools. Generators usually use combinations of static fuzzing vectors (known-to-be-dangerous values), or totally random data.

A fuzzer can be categorized in several ways: 1. A fuzzer can be generation-based or mutation-based depending on whether inputs are generated from scratch or by modifying existing inputs. 2. A fuzzer can be dumb (unstructured) or smart (structured) depending on whether it is aware of input structure. WebHonggfuzz a feedback-driven, easy-to-use fuzzer with interesting analysis options.
