Features

• 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 or from the terminal
• 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 Tor
• Ability to run behind multiple proxy types (socks4, socks5, http, https)
• Ability to use a random user agent, personal user agent, or custom default user agent
• More to come...

Installation
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

Proof of concept
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? Let's check what the HTTP headers server and cookies say:

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

Web Application Firewall using DFA - Raptor WAF v0.2

Raptor WAF is a simple web application firewall made in C, using KISS principle, to make poll use select() function, is not better than epoll() or kqueue() from *BSD but is portable,  the core of match engine using DFA to detect XSS, SQLi and path traversal.

No more words, look at the following :

WAF stands for Web Application Firewall. It is widely used nowadays to detect and defend SQL Injections and XSS...

• You can block XSS, SQL injection attacks and path traversal with Raptor
• You can use blacklist of IPs to block some users at config/blacklist ip.txt
• You can use IPv6 and IPv4 at communications
• At the future DoS protector, request limit, rule interpreter and Malware detector at uploads.
• At the future SSL/TLS...

to run:

$ git clone https://github.com/CoolerVoid/raptor_waf
$ cd raptor_waf; make; bin/raptor

Example

Up some HTTPd server at port 80

$ bin/Raptor -h localhost -p 80 -r 8883 -w 4 -o loglog.txt

you can test at http://localhost:8883/test.php

Look the docs

https://github.com/CoolerVoid/raptor_waf/blob/master/doc/raptor.pdf

Tests:

509 of attacks, detect and block 349, 68% of attacks blocked

Steps to create your WAF(web application firewall) in C

Following definition (like OWASP), a WAF is a piece of software intended to protect a web app that is on the level of the application. nowadays, a WAF is not defined by the web app, it’s not a customized solution specific to that application but similarly to a general software firewall, where one that contains parameters to protect against intrusion in a wide variety of frameworks and codes. Trying clear your mind, there is overlap between the different types of firewalls. Software and hardware firewalls are used in their own right to protect networks. However, WAFs with their specialized function for web applications, can take the form input of either of those two main types. Per default, a firewall uses a blacklist, protecting against an individual, previously logged attacks. Additionally, it can also use a white list, providing allowable users and instances of interaction for the application, another function is block SQL Injection attacks and XSS attacks… Another context  WAFs can create random tokens and put in forms to try blocks web robots and automated attacks, this practice can try mitigate CSRF pitfalls. Before you ask “How i can do  it?”, i gotta bring to you some principles, anyway the theory around facts…

Have two common WAFs:

1- Uses plugin in HTTPd to get information of data INPUT or OUTPUT, before finish he gets the request and block some contents, this function focuses at HTTP METHODs POST, GET…  

 2- This way, is my favorite, is a independent reverse proxy server, he bring all requests of the client to the proxy, the proxy makes some analysis in the content, if not block, he send all the information to the external server… 

  

Number One is a cold, this path is not fully portable… other bad thing you need create a diferent plugin each HTTPd, something to apache another to NGINX, IIs, lighttpd…  its not cool! If you are not a good low level programmer… you can try use twisted of python, is easy make reverse proxy with it, but is not good way, because not have good performance in production… if you piss off for it, study the Stevens book of sockets. Its OK, the title of this post is “create waf in C”, Task fully done here and commented and with some documentations in LaTex… relax, you can get it in this repository:

Identifies and Fingerprints Web Application Firewall (WAF) Products - WAFW00F

WAFW00F allows one to identify and fingerprint Web Application Firewall (WAF) products protecting a website.

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 the main site, github.com/sandrogauci/wafw00f .

What does it detect?

It detects a number of WAFs. To view which WAFs it is able to detect run WAFW00F with the -l option. At the time of writing the output is as follows:

$ ./wafw00f -l

                                 ^     ^
        _   __  _   ____ _   __  _    _   ____
