How does it work?
To do its magic, WAFW00F does the following:
- Sends a normal HTTP request and analyses the response; this identifies a number of WAF solutions.
- If that is not successful, it sends a number of (potentially malicious) HTTP requests and uses simple logic to deduce which WAF it is.
- If that is also not successful, it analyses the responses previously returned and uses another simple algorithm to guess if a WAF or security solution is actively responding to our attacks.
For further details, check out the source code on our main repository.
What does it detect?
WAFW00F can detect a number of firewalls, a list of which is as below:

How do I use it?
First, install the tools as described here.
For help you can make use of the --help
option. The basic usage is to pass an URL as an argument. Example:
$ wafw00f https://example.org ______ / \ ( W00f! ) \ ____/ ,, __ 404 Hack Not Found |`-.__ / / __ __ /" _/ /_/ \ \ / / *===* / \ \_/ / 405 Not Allowed / )__// \ / /| / /---` 403 Forbidden \\/` \ | / _ \ `\ /_\\_ 502 Bad Gateway / / \ \ 500 Internal Error `_____``-` /_/ \_\ ~ WAFW00F : v2.0.0 ~ The Web Application Firewall Fingerprinting Toolkit [*] Checking https://example.org [+] The site https://example.org is behind Edgecast (Verizon Digital Media) WAF. [~] Number of requests: 2
How do I install it?
The following should do the trick:
python setup.py install
Usage
Arguments List
$ wafw00f -h ______ / \ ( Woof! ) \______/ ) ,, ) (_ .-. - _______ ( |__| ()``; |==|_______) .)|__| / (' /|\ ( |__| ( / ) / | \ . |__| \(_)_)) / | \ |__| WAFW00F - Web Application Firewall Detection Tool (v2.0.0) Usage: wafw00f url1 [url2 [url3 ... ]] Example: wafw00f http://www.victim.org/ Options: -h, --help show this help message and exit -v, --verbose Enable verbosity, multiple -v options increase verbosity -a, --findall Find all WAFs which match the signatures, do not stop testing on the first one -r, --noredirect Do not follow redirections given by 3xx responses -t TEST, --test=TEST Test for one specific WAF -l, --list List all WAFs that WAFW00F is able to detect -p PROXY, --proxy=PROXY Use an HTTP proxy to perform requests, examples: http://hostname:8080, socks5://hostname:1080, http://user:pass@hostname:8080 -V, --version Print out the current version of WafW00f and exit. -H HEADERS, --headers=HEADERS Pass custom headers via a text file to overwrite the default header set.
Testing a Single URL
The URL can be directly supplied to the script after WAFW00F has been built and installed on the system.
wafw00f http://example.com
Testing Multiple URLs
Multiple URLs can be supplied one after another using spaces.
wafw00f http://example.com http://host.com http://site.tld
Listing All Supported WAFs
Option: -l
or --list
This option lists all the available supported WAF products by WAFW00F. With this option the companies manufacturing the WAF product can also be viewed alongside the WAF name.
wafw00f --list
Adding Custom Headers
Option: -H
or --headers
WAFW00F has its own set of default headers by which it makes the requests. The headers are specifically suited for emulating a Chrome browser running on a Windows platform. This option enables you to supply a comma separated list of custom headers which you might want WAFW00F to use during all requests.
wafw00f http://example.com -H headers.txt
NOTE: The headers which you will supply will overwrite the list of default headers.
Using Proxies
Option: -p
or --proxy
With this option, you can use proxies to route the requests through. The scheme should be in the normal URL format <scheme>://<username:password>@<hostname>:<port>
, where the username
and password
can be used in cases where the proxy server supports authentication.
wafw00f http://example.com -p http://user:pass@127.0.0.1:8080
Testing For A Single WAF Instance
Option: -t
or --test
This option helps you set WAFW00F to test for a single instance of a WAF. When this argument is supplied, WAFW00F will test and try to match the fingerprint for the given WAF only. The supplied WAF name should be equal to at least one of the names within wafprio.py
. You can use the --list
argument to list the products supported by the WAF.
wafw00f http://example.com -t 'Edgecast (Verizon Digital Media)'
Testing For All Possible WAF Instances
Option: -a
or --findall
This option helps set WAFW00F on a run and lets you enumerate all possible instances of a WAF on the site being tested. The logic behind this is that WAFW00F continues testing and matching fingerprints throughout its database and doesn’t exclusively stop on the first matched instance.
wafw00f http://example.com -a
Controlling Verbosity
Option: -v ...
This option helps set the verbosity level of the output. You can supply multiple instances of the argument for a better verbose output. More the number of -v
s, more verbose is the output.
wafw00f http://example.com -v -v
Version & License
Option: -V
or --version
This option displays the current version of WAFW00F from wafw00f/__init__.py
which you’re using.
wafw00f --version
