password brute force attacks

BruteLoops

A dead-simple library providing the foundational logic for efficient password brute force attacks against authentication interfaces.

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:

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 the 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
    • Timestamps associated with each authentication event are tracked in BruteLoops’ SQLite database. Each username receives a distinct timestamp to assure that authentication event 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 be 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.
