WIP: Adding I/O Feature to wafw00f
Latest commit e2da63f Jan 21, 2020


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

               /      \                                               
              (  W00f! )                                              
               \  ____/
