Wafw00F: The Web Application Firewall Fingerprinting Tool

Posted on 5:17 PM by Tina

How does wafw00f work?
   To do its magic, WAFW00F does the following steps:

  • Sends a normal HTTP request and analyses the response; this identifies a number of WAF solutions.
  • If that is not successful, wafw00f sends a number of (potentially malicious) HTTP requests and uses simple logic to deduce which WAF it is.
  • If that is also not successful, wafw00f analyses the responses previously returned and uses another simple algorithm to guess if a WAF or security solution is actively responding to wafw00f's attacks.

   For further details, check out the source code on EnableSecurity's main repository.
