The Web Application Firewall Fingerprinting Tool.
— From Enable Security

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:

$ wafw00f -l

                  /      \
                 (  Woof! )
                  \  ____/                      )
                  ,,                           ) (_
             .-. -    _______                 ( |__|
            ()``; |==|_______)                .)|__|
            / ('        /|\                  (  |__|
        (  /  )        / | \                  . |__|
         \(_)_))      /  |  \                   |__|
