I was curious if I could script a dictionary attack against one of the OSX Lion File Vault v2 encrypted external drives. If you haven’t done it. You need to be on Lion. Grab a spare USB storage stick. Make sure to backup any data from the device first. Encrypting the device by the book will erase and destroy the existing contents.

1. Go into “Disk Utility”
2. Plug in the desired USB storage stick
3. Click on the device in the list
4. Click on the Erase tab
5. Pull down the Format box and choose one of the Encrypted options like: Mac OS Extended (Journaled, Encrypted)
6. Click Erase
7. When prompted provide a desired password.

Now that you have setup an encrypted device you can use that to test this process.

1. First eject the usb device
2. Unplug it
3. Plug it back in
4. Click cancel and do not enter the passphrase

Now onto the rest of the process.

We wrap up our tutorial series on AccessData’s Distributed Network Attack (DNA) password recovery software with Amazon EC2 worker agents.

In this part we spin our custom AMI instance up and install the DNA worker agent.  Then we spin up a total of 20 of the dual core instances to see the password attempt throughput.

You will run up costs by running instances. I am not legally nor financially responsible for your use or how you use these tutorials. Please only do things you are legally and financially authorized for.  It is on you.

I have not ironed out the HTML5 player fall back to flash issue yet.  So if you cannot play the video in this post you can download it HERE or watch it over in my YouTube Channel.

We continue our tutorial series on AccessData’s Distributed Network Attack (DNA) password recovery software with Amazon EC2 worker agents.  We move into Amazon EC2 and what you need to know about the service itself.  In part three we will cover starting up an instance based on an exisiting Amazon Machine Image (AMI), logging into it and adding the packages we need to prepare it as a worker.

Keep in mind as we are moving into Amazon Web Services, even if you use the free tier account our tutorial touches on instances and data transfers that might incur costs.  Hopefully they are small per Amazon’s wonderful pricing.
