Installing boofuzz


Boofuzz requires Python ≥ 3.8. Recommended installation requires pip. As a base requirement, the following packages are needed:


sudo apt-get install python3-pip python3-venv build-essential


sudo zypper install python3-devel gcc


sudo yum install python3-devel gcc


It is strongly recommended to set up boofuzz in a virtual environment (venv). First, create a directory that will hold our boofuzz install:

$ mkdir boofuzz && cd boofuzz
$ python3 -m venv env

This creates a new virtual environment env in the current folder. Note that the Python version in a virtual environment is fixed and chosen at its creation. Unlike global installs, within a virtual environment python is aliased to the Python version of the virtual environment.

Next, activate the virtual environment:

$ source env/bin/activate

Or, if you are on Windows:

> env\Scripts\activate.bat

Ensure you have the latest version of both pip and setuptools:

(env) $ pip install -U pip setuptools

Finally, install boofuzz:

(env) $ pip install boofuzz

To run and test your fuzzing scripts, make sure to always activate the virtual environment beforehand.

From Source

  1. Like above, it is recommended to set up a virtual environment. Depending on your concrete setup, this is largely equivalent to the steps outlined above. Make sure to upgrade setuptools and pip or poetry.

  2. Download the source code. You can either grab a zip from or directly clone it with git:

    $ git clone

Install with Poetry

Poetry will automatically create a virtual environment for you and install the required dependencies. The installation will be editable by default, meaning that changes to the source code will be seen directly without reinstalling.

Simply execute the following command inside the boofuzz source dir:

$ poetry install

To install with extra dependencies like dev or docs, specify them in one of the following ways:

$ poetry install --extras "dev"
$ poetry install -E docs
$ poetry install --all-extras

Install with Pip

Run pip from within the boofuzz directory after activating the virtual environment:

$ pip install .


  • Use the -e option for developer mode, which allows changes to be seen automatically without reinstalling:

    $ pip install -e .
  • To install developer tools (unit test dependencies, test runners, etc.) as well:

    $ pip install -e .[dev]
  • If you’re behind a proxy:

    $ set HTTPS_PROXY=
  • If you’re planning on developing boofuzz itself, you can save a directory and create your virtual environment after you’ve cloned the source code (so env/ is within the main boofuzz directory).


The process monitor is a tool for detecting crashes and restarting an application on Windows or Linux. While boofuzz typically runs on a different machine than the target, the process monitor must run on the target machine itself.

The network monitor was Sulley’s primary tool for recording test data, and has been replaced with boofuzz’s logging mechanisms. However, some people still prefer the PCAP approach.


The network monitor requires Pcapy and Impacket, which will not be automatically installed with boofuzz. You can manually install them with pip install pcapy impacket.

If you run into errors, check out the Pcapy requirements on the project page.
