Learn how to inspect software for bugs using a proven fuzzing tool

WinAFL Fuzzing

AFL is a popular fuzzing tool for coverage-guided fuzzing. In this bootcamp, you will learn the basics of how to fuzz closed-source binaries with WinAFL.

Our target will be a test DLL vulnerable with a stack-overflow vulnerability. You will learn how to build a fuzzing harness, optimize it for maximum performance, and triage the bugs that it discovers.

This bootcamp covers:

Introduction to coverage-based fuzzing
Fundamental C programming for writing harnesses
Installing and configuring WinAFL
Developing and optimizing fuzzing harnesses
Achieving maximum code coverage
Triaging crashes to identify which ones are security bugs

Course Overview

AFL fuzzer is a program that looks for bugs in other programs by repeatedly running them with different inputs. It is mainly used to find security vulnerabilities in software. To do this, AFL first creates a large number of random test inputs. It then runs the program with each input and looks for crashes. If the program crashes, AFL assumes that there is a bug and records the input that caused the crash. This process is repeated until AFL has found a large number of different inputs that cause crashes.

This bootcamp will teach you how to use WinAFL to find vulnerabilities in Windows programs.

Writing Fuzzing Harnesses

A fuzzing harness is code that is written specifically to interact with the code or system under test in order to provide input (fuzz) and monitor the results. The main purpose of a fuzzing harness is to find bugs and security vulnerabilities.

Optimizing Fuzzing Harnesses

By optimizing fuzzing harnesses, we can make sure that they are more effective at finding vulnerabilities. Additionally, optimizing fuzzing harnesses can help to reduce the time it takes to find vulnerabilities.

Triaging Bugs

By triaging, you can identify which bugs are the most severe and need to be fixed first, and which can be safely ignored or deferred for later. This can save a lot of time and effort in the long run, and can help to make sure that the most critical software bugs are fixed as quickly as possible.

Training Modules

This course provides you with multiple training modules, each of which is designed to teach you practical skills that can help you solve important cyber problems. Each module offers exercises that will help you build your skills and capabilities.

WA-01: Introduction to C programming - 5 exercises
