I have some bad news. Your website may be vulnerable to a brute force login attack. This is a form of hacking in which an attacker tries thousands of usernames and passwords in order to identify the correct login for a site, or to gain access to sensitive information on the site. Want to check it out?
Web Brutator is Fast Modular Web Interfaces Bruteforcer.

-U, --userlist USERLIST Usernames list
-p, --password PASSWORD Single password
-P, --passlist PASSLIST Passwords list
-C, --combolist COMBOLIST Combos username:password 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:
- Create a new file with appropriate name under
lib/core/modules/
- 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 byRequester
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
- Module is then automatically available (check using
-l
option) from the command-line. - Test the module to make sure it is working as expected !
- Make a pull request to add the module to the project 😉
