We used to have a little comfort that if someone got a hole of your password hashes, it would at least take them considerable time to crack and extract the passwords.
Those days are gone !
Brute force cracking password hashes is becoming too easy thanks to apps that make use of the multiple cores in graphics cards.
CPU Password cracking
Core 2 Duo 2.13 GHz - 2.5 Million Hashes / Second
Core i7 980x - 19. Million Hashes / Second
GPU Password cracking
Radeon HD 5830 ($109) - 290 Million Hashes / Second
Radeon HD 6990 (($740) - 760 Million Hashes / Second
Multi GPU setups can achieve staggering rates of performance.
The White Pixel system (http://whitepixel.zorinaq.com/) has 4 AMD Radeon HD 5970 graphics cards and custom software. (each 5970 Card has dual GPU ‘s and costs around $400).
it can churn through more than 33 Billion Password hashes per second.
What's the best Alternative to passwords ?
