🚀 Available Modules

• axis2
• coldfusion
• glassfish
• htaccess
• jboss
• jenkins
• joomla
• railo
• standardform
• tomcat
• weblogic
• websphere

Notice: Some products implement account lockout after a given number of failed authentication attempts, by default (e.g. Weblogic, Tomcat…). web-brutator notices the user at the beginning of bruteforce attack if it is the case. Take this into account before launching bruteforce on such targets.

💡 Standard web authentication form Auto-Detection

web-brutator can automatically detect standard web authentication forms and perform bruteforce automatically. This feature is available via the module standardform, it is still experimental and can lead to false positives/negatives since it is based on several heuristics.

Not supported:

• Web authentication using Javascript;
• Authentication with CAPTCHA;
• 2-step authentication …

Example:

python3 web-brutator.py --target standardform --url https://mytarget.com -U ./usernames.txt -P ./passwords.txt -s -t 40 -v

This demo is against a phpMyAdmin interface

🔧 Add new module / Contribute

Adding a new authentication bruteforce module is pretty straightforward:

1. Create a new file with appropriate name under lib/core/modules/
2. Create a class in this file, using the following template. Development is very easy, check any existing module under lib/core/modules/ for some examples. Note that HTTP requests should be done via the static methods provided by Requester class: Requester.get(), Requester.post(), Requester.http_auth().

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from lib.core.Exceptions import AuthException, RequestException
from lib.core.Logger import logger
from lib.core.Requester import AuthMode, Requester


class Mymodule:

    def __init__(self, url, verbose=False):
        self.url = url
        # Other self variables can go here


    def check(self):
    	"""
    	This method is used to detect the presence of the targeted authentication
    	interface.
    	:return: Boolean indicating if the authentication interface has been detected
    	"""
    	# Implement code here


    def try_auth(self, username, password):
    	"""
    	This method is used to perform one authentication attempt.
    	:param str username: Username to check
    	:param str password: Password to check
    	:return: Boolean indicating authentication status
    	:raise AuthException:
    	"""
        # Implement code here        

3. Module is then automatically available (check using -l option) from the command-line.
4. Test the module to make sure it is working as expected !
5. Make a pull request to add the module to the project 😉
