Available Modules

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 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:


python3 --target standardform --url -U ./usernames.txt -P ./passwords.txt -s -t 40 -v

Add 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.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
: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

  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 😉
