Fuzzing for fun and profit

Syed (~syedkhalid)


What is Fuzzing?

"Fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program". Fuzzing is a very common method used by security researchers to discover bugs because auditing the source code of a large project is a tedious process and time consuming. Fuzzing not only helps to discover security bugs but also helps to improve the stability of your software.

About this talk

This talk will emphasize much on "Why python is the language of choice for Fuzzing?" and also discuss about the most used fuzzing frameworks written in python. This talk will give a overview of the different types of fuzzer and how to build a large scale fuzzing setup. A short demo of Sulley framework and python-afl will be shown in the presentation.
