Launching a new online WPA/WPA2 Hash Cracking Service

Hey all, just wanted to create a post for a side project I have been working on and recently released to the public. It’s a online WIFI hash cracking service. Basically when you capture a WIFI handshake you will need to crack it and not everyone has the tools to crack the password since cracking WPA hashes can be slow and take up a lot of resources. I had an old mining rig laying around and decided to bring it back to life and help the hash cracking community. I always have loved WIFI and the learning on how it works and different ways of “hacking” WIFI which is what gave me an interest in this project. I also enjoyed cracking hashes and learning the passwords people use. Every time there was any sort of data breech I would always download the hashed passwords and try to crack as many of them as I can to build a decent sized password wordlist as well as to get an understanding of what passwords people are using.

The service is called Cr4ck.io and basically you can upload a .cap or .hccapx file and it will run a basic wordlist to try and crack the handshake hash. It will run through around 30 million common WIFI passwords and has a decent success rate of around 30%. The service is free to run but if it does crack the WIFI hash then there is a small fee to reveal the cracked hash. As of writing this article the fee is $10 and can be paid using Bitcoin or Etherium.

I hope to continue running this project for as long as I can and hope that you can use it to test your own network to see if it can crack your WIFI password. Please let me know if you have any questions or suggestions and please join the forums on the website if you need any help or want to share password cracking tips.

How to Crack WPA2 WiFi Networks using the Raspberry Pi

Cracking WPA and WPA 2 networks is still very difficult and solely dependent on using a brute force attack with a good dictonary. Depending on the word-list that you use will improve the success rate of cracking WPA2 WiFi networks. In this tutorial I will be showing you how to grab the 4-Way handshake from a WPA2 WiFi network and how to do an offline brute-force cracking attempt at find the password for the WiFi network. The Raspberry Pi 3 can check around 500 keys per second which is not really fast when you have a word-list with over 10 millions passwords to check.

The Raspberry Pi 3 can check around 1.8 million passwords an hour which again it doesn’t gurantee that it will be able to find the correct password for a WPA2 WiFi network. The best use of the Raspberry Pi in hacking WiFi networks is that you can use it to collect a 4-Way handshake and then transfer the handshake for cracking to a more powerful computer. The reason the Raspberry Pi is good for a scenrio like this is because of its mobility. You can easilly attach a battery to your Pi and put it in a backback and walk around collecting handshakes to crack.

Today’s tutorial will show you how to capture a 4-Way Handshake and then use our Raspberry Pi 3 to crack the password. We will be using the aircrack-ng suite to collect the handshake and then to crack the password. You will need a good word-list for cracking. There are many word-lists out there. One of the biggest word-lists I have seen is the CrackStation Wordlist which has over 1.5 Billion passwords that have been put together from many data breaches like Linked In and MySpace. Let’s get started.

Objective

To capture a 4-Way Handshake from a WPA2 WiFi network and crack the password using a brute-force method

Material

You will need the following:

Instructions

I will be running a freshly installed version of Raspbian Jessie on my Raspberry Pi. You can use Rasbian Jessie Lite on your Raspberry Pi since we will just needing the terminal and I will be using SSH to run all my commands. Go ahead and connect to your Raspberry Pi and lets begin by installing the aircrack-ng suite on our Raspberry Pi. Run the following command to install the dependencies for the aircrack-ng suite: Continue Reading
