In this article, we gonna see how to use the wafw00f tool to detect the WAFs or Web Application Firewall. The wafw00f has multiple techniques to detect or identify the WAF like normal response analysis, send the malicious request and its response analysis, some guessing techniques, etc.
How does wafw00f 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 EnableSecurity’s main repository.
Installing wafw00f tool
We can download the zip package from the official GitHub repository.
Or you can clone the repository using git client. Follow the commands to get the package.
$ git clone https://github.com/EnableSecurity/wafw00f.git Cloning into 'wafw00f'... remote: Enumerating objects: 244, done. remote: Counting objects: 100% (244/244), done. remote: Compressing objects: 100% (221/221), done. remote: Total 4170 (delta 192), reused 35 (delta 23), pack-reused 3926 Receiving objects: 100% (4170/4170), 643.37 KiB | 152.00 KiB/s, done. Resolving deltas: 100% (3019/3019), done.
Navigate to the wafw00f directory and run the following command to install the wafw00f tool in the system.
$ python setup.py install # this will process the setup file and install wafw00f in the system
wafw00f help command
For help you can make use of the --help option.
$ wafw00f --help
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
-o OUTPUT, --output=OUTPUT
Write output to csv, json or text file depending on
file extension. For stdout, specify - as filename.
-i INPUT, --input-file=INPUT
Read targets from a file. Input format can be csv,
json or text. For csv and json, a `url` column name or
element is required.
-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.
List of WAFs can be detected by wafw00f
WAFW00F can detect a number of firewalls, we can list the firewalls that can be detected by the wafwOOf tool.

The Web Application Firewall Fingerprinting Toolkit
[*] Checking http://example.com/
[+] The site http://example.com/ is behind Edgecast (Verizon Digital Media) WAF.
[~] Number of requests: 2
So, thats how the wafw00f tool can detect or identify the WAF or Web application Firewall.
