cudaHashCat 1.21.7 on EC2 Setup Tutorial (Cloud Hash Cracking 2014)
Recently, I needed to crack some hashes fast, and without any extra hardware, I took a look at EC2.
There were some really great tutorials out there, and some even better scripts that automated the process.
Finally you should be able to bench mark it using:
You will probably want some wordlists for your cracking, I've assembled a collection of wordlist collections here, with a little bit on creating customized wordlists.
And best of all, it works :) Here's cracking some MD5(Unix) passwords, and here's to cracking more!
There were some really great tutorials out there, and some even better scripts that automated the process.
My problem with the script, is that it dosn't work for the current version of HashCat (this is due to the hardcoded driver versions, and hashcat only offers the new version on their site) .. So I've made an updated tutorial that works at the time of writing (although it also has hardcoded driver versions, and one day may stop working). So let's fire up AWS, and get into our EC2 console.
Under the 'Instances' tab, click 'Launch Instance', then select 'Community AMIs', and search for 'ami-4fad7426'. 'Select' the instance, then check 'GPU instances', type 'g2.2xlarge', then click 'Review and Launch'. You will probably want to check the 'Storage', and increase the root drive to something a little lager than 8gigs, you will probably want to store some wordlists on the disk. Launch it then you should be able to log in as 'ubuntu' with your select ssh key.
Next, run the following upgrade script, and please let me know if you have any issues.
