Kraken is an online distributed brute force password cracking tool. It allows you to parallelize dictionaries and crunch word generator based cracking across multiple machines both as a web app in a web browser and as a standalone electron based client. Kraken aims to be easy to use, fault tolerant and scalable.
I wrote Kraken because I wanted to learn more about offensive security and to write an easy solution to overcome the limitation of using a single device when attempting distribute brute force workloads.
Kraken is a dockerized application using docker-compose which will launch the db (Postgres), s3 compliant file storage (Minio), the server and the browser client. You can find the docker-compose file at the root directory of the repository. You can deploy it using the following command:
docker-compose up
Kraken’s Browser Client should be accessible at:
Note: To run the Browser Client from a remote machine, you MUST use HTTPS for both server url and browser url. Eg. If you are hosting the server on 192.168.1.2, then browser client will be available at https://192.168.1.2:8443 and the server url should be https://192.168.1.2:8443/api
To upload password lists or dictionaries, upload them to Minio Console at localhost:9001. View steps below for a detailed guide Otherwise, you can generate word lists dynamically using crunch. See crunch options and how to use them here: crunch man page
Kraken’s server runs on localhost:5000 and also hosts swagger documentation at localhost:5000/swagger.
The desktop client is an electron based portable application and can be run on Mac, Windows and Linux. Due to sensitive permissions required to function, it is highly recommended that you compile and it yourself by cloning the repo and using :
cd kraken-client
npm install
npm run electron-start
Note: Window EXE portable client needs to run in the folder with its hashcat dependencies. Hashcat files can be dowloaded from their home page or here. Ive included a compressed zip file with the portable executable and required hashcat files. They can be downloaded:
Releases include a Linux AppImage which only requires hashcat to be installed.
Install hashcat:
sudo apt-get install hashcat
You will have to give AppImage permission via properties to execute.

The timeout command in Linux runs a command with a time limit and terminates it when the limit is reached. It is part of GNU coreutils, available on virtually every Linux distribution. It is most useful for commands with no built-in timeout option, such as ping, curl, tcpdump, or a custom script that might hang indefinitely. How the timeout Command Works in Linux The syntax is: bashtimeout [OPTIONS] DURATION COMMAND [ARG]...…
