According to an article in SC Magazine, Global Secure Systems reports that a Russian firm using the latest Nvidia graphics card has managed to accelerate WiFi ‘Password recovery’ times by up 10,000 percent.

From David Hobson, managing director of GSS:

Brute force decryption of the WPA and WPA2 systems using parallel processing has been on the theoretical possibilities horizon for some time – and presumably employed by relevant government agencies in extreme situations – but the use of the latest NVidia cards to speedup decryption on a standard PC is extremely worrying.

Hobson goes on to say that businesses using WiFi should add another layer of security to their networks, namely by adding VPN encryption into the mix.

Yikes! Honestly though, we were probably heading in that direction anyways. Not to mention, and please correct me if I’m wrong, this is a brute force attack, albeit a very powerful brute force attack, which relies on weak passphrases. A randomly generated strong password should still be able to resist such attacks.

Then again, I’m no security expert, I just play one on my website.
