WhatWaf is an advanced firewall detection tool who's goal is to give you the idea of "There's a WAF?". WhatWaf works by detecting a firewall on a web application, and attempting to detect a bypass (or two) for said firewall, on the specified target.

• Ability to run on a single URL with the -u/--url flag
• Ability to run through a list of URL's with the -l/--list flag
• Ability to detect over 40 different firewalls
• Ability to try over 20 different tampering techniques
• Ability to pass your own payloads either from a file, from the terminal, or use the default payloads
• Default payloads that are guaranteed to produce at least one WAF triggering
• Ability to bypass firewalls using both SQLi techniques and cross site scripting techniques
• Ability to run behind multiple proxy types (socks4, socks5, http, https and Tor)
• Ability to use a random user agent, personal user agent, or custom default user agent
• Auto assign protocol to HTTP or ability to force protocol to HTTPS
• A built in encoder so you can encode your payloads into the discovered bypasses
• More to come...

Installing whatwaf is super easy, all you have to do is the following:

Have Python 2.7, Python 3.x compatibility is being implemented soon:

sudo -s << EOF
git clone https://github.com/ekultek/whatwaf.git
cd whatwaf
chmod +x whatwaf.py
pip2 install -r requirements.txt
./whatwaf.py --help

First we'll run the website through WhatWaf and figure out which firewall protects it (if any):

Next we'll go to that website and see what the page looks like:

Hmm.. that doesn't really look like Cloudflare does it? Lets see what the headers say:

And finally, lets try one of the bypasses that it tells us to try:

If you want to make some tamper scripts, want to add some functionality or just want to make something look better. Getting involved is easy:

1. Fork the repository
2. Edit the code to your liking
3. Send a pull request

I'm always looking for some helpful people out there, and would love help with this little side project I got going on, Thanks!
