        # Honggfuzz

## Description

A security oriented, feedback-driven, evolutionary, easy-to-use fuzzer with interesting analysis options. See the [Usage document](https://github.com/google/honggfuzz/blob/master/docs/USAGE.md) for a primer on Honggfuzz use.

## Code

  * Latest stable version: [2.6](https://github.com/google/honggfuzz/releases)

  * [Changelog](https://github.com/google/honggfuzz/blob/master/CHANGELOG)

## Installation

```

sudo apt-get install binutils-dev libunwind-dev libblocksruntime-dev clang

make

```

## Features

  * It's __multi-process__ and __multi-threaded__: there's no need to run multiple copies of your fuzzer, as honggfuzz can unlock potential of all your available CPU cores with a single running instance. The file corpus is automatically shared and improved between all fuzzed processes.

  * It's blazingly fast when the [persistent fuzzing mode](https://github.com/google/honggfuzz/blob/master/docs/PersistentFuzzing.md) is used. A simple/empty _LLVMFuzzerTestOneInput_ function can be tested with __up to 1mo iterations per second__ on a relatively modern CPU (e.g. i7-6700K).

  * Has a [solid track record](#trophies) of uncovered security bugs: the __only__ (to the date) __vulnerability in OpenSSL with the [critical](https://www.openssl.org/news/secadv/20160926.txt) score mark__ was discovered by honggfuzz. See the [Trophies](#trophies) paragraph for the summary of findings to the date.

  * Uses low-level interfaces to monitor processes (e.g. _ptrace_ under Linux and NetBSD). As opposed to other fuzzers, it __will discover and report hijacked/ignored signals from crashes__ (intercepted and potentially hidden by a fuzzed program).

  * Easy-to-use, feed it a simple corpus directory (can even be empty for the [feedback-driven fuzzing](https://github.com/google/honggfuzz/blob/master/docs/FeedbackDrivenFuzzing.md)), and it will work its way up, expanding it by utilizing feedback-based coverage metrics.

  * Supports several (more than any other coverage-based feedback-driven fuzzer) hardware-based (CPU: branch/instruction counting, __Intel BTS__, __Intel PT__) and software-based [feedback-driven fuzzing](https://github.com/google/honggfuzz/blob/master/docs/FeedbackDrivenFuzzing.md) modes. Also, see the new __[qemu mode](https://github.com/google/honggfuzz/tree/master/qemu_mode)__ for blackbox binary fuzzing.

  * Works (at least) under GNU/Linux, FreeBSD, NetBSD, Mac OS X, Windows/CygWin and [Android](https://github.com/google/honggfuzz/blob/master/docs/Android.md).

  * Supports the __persistent fuzzing mode__ (long-lived process calling a fuzzed API repeatedly). More on that can be found [here](https://github.com/google/honggfuzz/blob/master/docs/PersistentFuzzing.md).

  * It comes with the __[examples](https://github.com/google/honggfuzz/tree/master/examples) directory__, consisting of real world fuzz setups for widely-used software (e.g. Apache HTTPS, OpenSSL, libjpeg etc.).

  * Provides a __[corpus minimization](https://github.com/google/honggfuzz/blob/master/docs/USAGE.md#corpus-minimization--m)__ mode.

## Requirements

  * **Linux** - The BFD library (libbfd-dev) and libunwind (libunwind-dev/libunwind8-dev), clang-5.0 or higher for software-based coverage modes

  * **FreeBSD** - gmake, clang-5.0 or newer

  * **NetBSD** - gmake, clang, capstone, libBlocksRuntime

  * **Android** - Android SDK/NDK. Also see [this detailed doc](https://github.com/google/honggfuzz/blob/master/docs/Android.md) on how to build and run it

  * **Windows** - CygWin

  * **Darwin/OS X** - Xcode 10.8+

  * if **Clang/LLVM** is used to compile honggfuzz - link it with the BlocksRuntime Library (libblocksruntime-dev)
