CrackerJack – Web GUI for Hashcat

February 18, 2021

Web Interface for Hashcat by Context Information Security

Demo / Start Cracking in Under 5 Minutes

Introduction

CrackerJack is a Web GUI for Hashcat developed in Python.

Architecture

This project aims to keep the GUI and Hashcat independent. In a nutshell, here’s how it works:

User uploads hashes, selects wordlist/rules/mask etc, and clicks “start”.
Web server spawns a new screen.
- Generates the hashcat command based on the settings.
- Runs the command in the screen.
- Monitors the screen’s output, parses it, and displays in the GUI.

This allows CrackerJack to be future-proof as it ties to the input/output of Hashcat. Also, if the GUI is not working for whatever reason, hashcat will keep running.

Features

Minimal dependencies
- Uses sqlite3, screen, and hashcat.
Complete hashcat session management.
- Start/stop/pause/restore running sessions.
- Terminate cracking jobs after a specific date/time.
Web interface for mask generation (?a?l?u).
Web Push notifications when a password is cracked.
Swagger 2.0 API.
Create wordlists from already cracked passwords and feed back into the cracking session.
Session history to track which attacks you have already performed.
Multi-user support (local and/or LDAP).
Wordlist/Mask/Rule support.
Multiple theme support (Bootswatch).
Straight-forward setup.
- Entire configuration is via the GUI. No need for manually editing config files.
- Run locally on Linux and Windows (WSL).
- Install on a server using ansible scripts (Ubuntu 14/16/18 and CentOS 7/8).
- Easy backups – all user data are in the ./data directory.
Troubleshoot sessions via SSH.

Limitations

Not a solution for queueing jobs – it’s only for on-demand password cracking.
Not meant to be a replacement for command-line usage. It’s complimentary and only supports basic and most common cracking tasks.
Will not install any GPU drivers. The main assumption is that you have a cracking rig already setup and are looking for a Web GUI.
Wordlists and rules should already be present on the system.
