🚀 Documentation has moved 🚀

Instead of having a 1300 line README.md (sorry...), feroxbuster's documentation has moved to GitHub Pages. The move to hosting documentation on Pages should make it a LOT easier to find the information you're looking for, whatever that may be. Please check it out for anything you need beyond a quick-start. The new documentation can be found here.

😕 What the heck is a ferox anyway?

Ferox is short for Ferric Oxide. Ferric Oxide, simply put, is rust. The name rustbuster was taken, so I decided on a variation. 🤷

🤔 What's it do tho?

feroxbuster is a tool designed to perform Forced Browsing.

Forced browsing is an attack where the aim is to enumerate and access resources that are not referenced by the web application, but are still accessible by an attacker.

feroxbuster uses brute force combined with a wordlist to search for unlinked content in target directories. These resources may store sensitive information about web applications and operational systems, such as source code, credentials, internal network addressing, etc...

This attack is also known as Predictable Resource Location, File Enumeration, Directory Enumeration, and Resource Enumeration.

Quick Start

This section will cover the minimum amount of information to get up and running with feroxbuster. Please refer the the documentation, as it's much more comprehensive.

💿 Installation

There are quite a few other installation methods, but these snippets should cover the majority of users.


If you're using kali, this is the preferred install method. Installing from the repos adds a ferox-config.toml in /etc/feroxbuster/, adds command completion for bash, fish, and zsh, includes a man page entry, and installs feroxbuster itself.

sudo apt update && sudo apt install -y feroxbuster

Linux (32 and 64-bit) & MacOS

curl -sL https://raw.githubusercontent.com/epi052/feroxbuster/master/install-nix.sh | bash

Windows x86_64

Invoke-WebRequest https://github.com/epi052/feroxbuster/releases/latest/download/x86_64-windows-feroxbuster.exe.zip -OutFile feroxbuster.zip
Expand-Archive .\feroxbuster.zip
.\feroxbuster\feroxbuster.exe -V

All others

Please refer the the documentation.

🧰 Example Usage

Here are a few brief examples to get you started. Please note, feroxbuster can do a lot more than what's listed below. As a result, there are many more examples, with demonstration gifs that highlight specific features, in the documentation.

Multiple Values

Options that take multiple values are very flexible. Consider the following ways of specifying extensions:

./feroxbuster -u http://127.1 -x pdf -x js,html -x php txt json,docx

The command above adds .pdf, .js, .html, .php, .txt, .json, and .docx to each url

All of the methods above (multiple flags, space separated, comma separated, etc...) are valid and interchangeable. The same goes for urls, headers, status codes, queries, and size filters.

Include Headers

./feroxbuster -u http://127.1 -H Accept:application/json "Authorization: Bearer {token}"

IPv6, non-recursive scan with INFO-level logging enabled

./feroxbuster -u http://[::1] --no-recursion -vv

Read urls from STDIN; pipe only resulting urls out to another tool

cat targets | ./feroxbuster --stdin --silent -s 200 301 302 --redirects -x js | fff -s 200 -o js-files

Proxy traffic through Burp

./feroxbuster -u http://127.1 --insecure --proxy

Proxy traffic through a SOCKS proxy (including DNS lookups)

./feroxbuster -u http://127.1 --proxy socks5h://

Pass auth token via query parameter

./feroxbuster -u http://127.1 --query token=0123456789ABCDEF

🚀 Documentation has moved 🚀

For realsies, there used to be over 1300 lines in this README, but it's all been moved to the new documentation site. Go check it out!
