Version 0.2

usage: web-brutator.py [-h] [--url URL] [--target TYPE] [-u USERNAME]
[-U USERLIST] [-p PASSWORD] [-P PASSLIST]
[-C COMBOLIST] [-t THREADS] [-s] [-v] [-e MAX_ERRORS]
[--timeout TIMEOUT] [-l]

optional arguments:
-h, --help show this help message and exit
--url URL Target URL
--target TYPE Target type
-u, --username USERNAME Single username
-U, --userlist USERLIST Usernames list
-p, --password PASSWORD Single password
-P, --passlist PASSLIST Passwords list
-C, --combolist COMBOLIST Combos usernameassword list
-t, --threads THREADS Number of threads [1-50] (default: 10)
-s, --stoponsuccess Stop on success
-v, --verbose Print every tested creds
-e, --max-errors MAX_ERRORS Number of accepted consecutive errors (default: 10)
--timeout TIMEOUT Time limit on the response (default: 20s)
-l, --list-modules Display list of modules

Example:

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

? 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

DOWNLOAD​

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.
aram str username: Username to check
aram str password: Password to check
:return: Boolean indicating authentication status
:raise AuthException:
"""
# Implement code here

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