7MS #309: Password Cracking in the Cloud - Part 2

Cracking passwords in the cloud is super fun (listen to last week's episode to learn how to build your own cracking box on the cheap at Paperspace)!

In the last couple weeks, customers have asked me about doing a password strength assessment on their Active Directory environment. I asked around and read a bunch of blogs and found a method that I think:

  • Extracts the hashes safely
  • Parses down the dump to contain only the hashes (so that if somebody popped my Paperspace cloud-crackin' box, they'd have just a list of half-cracked hashes and that's it)
  • Does the work pretty automagically

I talk about this in more detail in today's podcast, and here's the gist you can follow with all the necessary commands to get AD crackin'!
