[ExT] How to Secure Yourself from GPU Password Cracking

post #1 of 2

The problem lies in the fact that GPUs are massively parallel, with hundreds of stream processors that can simultaneously crack password hashes. CPUs have always been notoriously bad at parallel processing, and even the advent of multi-core chips is nothing to write home about. Supercomputers with hundreds of CPUs obviously ameliorate the problem slightly -- but considering GPUs can also be used in supercomputing, it's probably just time to face facts: if you want an uncrackable password, you need to use some seriously long phrases.

I think the article was just OK, but interesting to read none the less...

lol, if they have physical access to your unencrypted hard drive you are toast any ways.

The real ways to protect your self have never changed since GPU cracking became possible years ago:

1. Keep intruders away physically.

2. Encrypt the drive (thus stops any access to the SAM DB).
