BruteLoops - Protocol Agnostic Online Password Guessing API

#391
Topic created · 1 Posts · 1 Views

  • A dead simple library providing the foundational logic for efficient password brute force attacks against authentication interfaces.
    See various Wiki sections for more information.
    A "modular" example is included with the library that demonstrates how to use this package. It's fully functional and provides multiple brute force modules. Below is a sample of its capabilities:
    authentication module for training/testing ">

    http.accellion_ftp  Accellion FTP HTTP interface login module  
    http.basic_digest   Generic HTTP basic digest auth  
    http.basic_ntlm     Generic HTTP basic NTLM authentication  
    http.global_protect  
    Global Protect web interface  
    http.mattermost     Mattermost login web interface  
    http.netwrix        Netwrix web login  
    http.okta           Okta JSON API  
    http.owa2010        OWA 2010 web interface  
    http.owa2016        OWA 2016 web interface  
    smb.smb             Target a single SMB server  
    testing.fake        Fake authentication module for training/testing  
    

    Key Features

    • Protocol agnostic - If a callback can be written in Python, BruteLoops can be used to attack it
    • SQLite support - All usernames, passwords, and credentials are maintained in an SQLite database.
    • A companion utility (dbmanager.py) that creates and manages input databases accompanies BruteLoops
    • Spray and Stuffing Attacks in One Tool - BruteLoops supports both spray and stuffing attacks in the same attack logic and database, meaning that you can configure a single database and run the attack without heavy reconfiguration and confusion.
    • Guess scheduling - Each username in the SQLite database is configured with a timestamp that is updated after each authentication event. This means we can significantly reduce likelihood of locking accounts by scheduling each authentication event with precision.
    • Fine-grained configurability to avoid lockout events - Microsoft's lockout policies can be matched 1-to-1 using BruteLoop's parameters:
    • auth_threshold = Lockout Threshold
    • max_auth_jitter = Lockout Observation Window
    • Timestampes associated with each authentication event are tracked in BruteLoops' SQLite database. Each username receives a distinct timestamp to assure that authentication events are highly controlled.
    • Attack resumption - Stopping and resuming an attack is possible without worrying about losing your place in the attack or locking accounts.
    • Multiprocessing - Speed up attacks using multiprocessing! By configuring the`parallel guess count, you're effectively telling BruteLoops how many usernames to guess in parallel.
    • Logging - Each authentication event can optionally logged to disk. This information can be useful during red teams by providing customers with a detailed attack timeline that can be mapped back to logged events.
      Dependencies
      BruteLoops requires Python3.7 or newer and SQLAlchemy 1.3.0, the latter of which can be obtained via pip and the requirements.txt file in this repository: python3.7 -m pip install -r requirements.txt
      Installation
    git clone https://github.com/arch4ngel/bruteloops  
    cd bruteloops  
    python3 -m pip install -r requirements.txt  
    

    How do I use this Damn Thing?
    Jeez, alright already...we can break an attack down into a few steps:
    0. Find an attackable service

    1. If one isn't already available in the example.py[1] directory, build a callback
    2. Find some usernames, passwords, and credentials
    3. Construct a database by passing the authentication data to dbmanager.py[2]
    4. If relevant, Enumerate or request the AD lockout policy to intelligently configure the attack
    5. Execute the attack in alignment with the target lockout policy[1][3][4]
