Implementing Fuzz Testing in CI/CD with AFL++
Overview
AFL++ (American Fuzzy Lop Plus Plus) is a community-maintained fork of AFL that provides state-of-the-art coverage-guided fuzz testing for discovering vulnerabilities in compiled applications. AFL++ uses genetic algorithms to mutate inputs, tracking code coverage to find new execution paths that trigger crashes, hangs, and undefined behavior. In CI/CD environments, AFL++ can be integrated to continuously test parsers, protocol handlers, file format processors, and any code that handles untrusted input. AFL++ supports persistent mode for high-speed fuzzing (up to 100,000+ executions per second), custom mutators, QEMU mode for binary-only fuzzing, and CmpLog/RedQueen for automatic dictionary extraction.

Prerequisites
- Linux-based CI runners (AFL++ does not support Windows natively)
- GCC or Clang compiler toolchain
- AFL++ installed (
apt install aflplusplus or built from source)
- Target application with harness functions isolating input processing
- Seed corpus of valid input samples
Core Concepts
This section covers core concepts for implementing fuzz testing in cicd with aflplusplus.
- Ensure all prerequisites are met before proceeding
- Follow the documented workflow steps in sequence
- Record results and any anomalies encountered during this phase
Coverage-Guided Fuzzing
AFL++ instruments the target binary at compile time (or via QEMU/Frida for binary-only targets) to track which code paths each input exercises. When a mutated input triggers a new code path, it is saved to the corpus for further mutation. This feedback loop enables AFL++ to systematically explore program state space.
