Found this on a friend’s Buzz page, rather scary.
Basically these guys offer access to a cluster that has been specifically fine tuned for cracking WPA encryption keys for wireless networks and at the cheapest price it’ll cost $17. I’ve seen people online build machines with multiple graphics cards and then run the code on them as well as the CPU as the graphics cards (Nvidia is the example I read) are faster at doing the math the desktop CPU’s.
Should we all panic? Well if you read the FAQ on the site you’ll see that WPA encryption is still a little hard to crack, changing the SSID of the access point to something unique makes it harder and so does choosing a non-dictionary password for the WPA key.
