A simplistic, minimalist deployment script and template to create a cracking ready EC2 instance. Awscracknip deploys an EC2 instance with a security group, ready to connect and deploys all that is needed to run hashcat and make use of NVIDIA Teslas.
There are already fancy aws based crackers out there, like e.g. https://github.com/c6fc/npk and other great ones. They work and are very sophisticated, but I could never fit them in my daily workflow, due to high complexity or long setup times.
This is why awscracknip is kept very basic intentionally so on the fly changes on the template or deployment can be made without the need to spend a day understanding complex code.
It can also be deployed and is ready within ~5 minutes.
As a good wordlist is key to cracking. I have mine in an EFS storage, which can be mounted from anywhere to add stuff to it. Awscracknip comes with all the tools to connect and mount such a storage. It does not deploy any kind of storage so one can make it fit to an existing wordlist storage solution or aws setup.
You need:
- An AWS account with sufficent service quota to deploy EC2 instances
- A keypair to connect via SSH
- aws cli installed on your machine where awscracknip is deployed
You might want:
- A EFS or EBS share where you store your wordlists
The efs-utils is installed on the deployed instance so mounting can be done.
Awscracknip installs everything with cloudformation. The default stack that gets deployed needs your SSH KeyName and the EC2 instance, which gets deployed. By default a g4dn.xlarge is selected if none is given. The output from aws cli is shown to make it easier to troubleshoot.
bash awscracknip.sh -install KeyName EC2Instance
While stack deployment is fast the scripts to make it ready to run hascat and install the drivers take a few minutes to finish.
The stack can be killed and the EC2 instance and its security group is deleted via
bash awscracknip.sh -kill
Use -info to display stack status as well as data, like IP-Address for the EC2
bash awscracknip.sh -info
In order to connect to the instance you can use
bash awscracknip.sh -connect
To not accumulate unwanted costs you can keep it running but suspend the EC2 via
bash awscracknip.sh -stop
and -start to wake it up again.
-connect assumes the key to be in the same folder as the deployment script, you can either change this in the script or connect however else you like.
Depends on your used storage and your EC2 instance plus runtime. A good place to check beforehand ist https://instances.vantage.sh/
For the default instance (g4dn.xlarge) and without storage costs, one can expect roughly 0,75€ per running hour. With the p3 instances this can go up to 20-25€ per hour. However these instances are very very powerfull. At this point this is basically pay2win.
