Re: Competition said by Pv8man:No I never saidf 15 min, you just have to wait in the car until someone is connected then you send a de auth packet, making them reconnect. Then once you captured the 4 way handshake packet, then you can take it home to be cracked on gpu Not quite, the fastest GPU that I'm aware of can do 11,000 KPS
Supposing the user used a large random characters key, your GPU would need a mean time of well over 100,000+ years.
That is assuming the best of conditions -- using a high speed linux tool like Jack The Ripper
Now suppose even a short key that is random - suppose 16 Characters - even then you will be waiting years and years. |

It won't take hundreds of years if you have Four Nvidia Tesla GPU's all SLI |

| Ok, where to start here...
First that is for MD5 hash sums, Not for RC cipher used on a standard router.
secondly much of the work is precomputed - the WPA cipher "salts" the pass-phrase based on the SSID making it immune to this type of attack ( even with a Precomputed hash table it still only works with dictionary attacks)
Completely wrong on all counts |

1 edit | said by DataRiker:The key is only as strong as one wants it to be. Using a simple keys like the video is highly misleading. The cipher is WPA is not broke nor has there even been a DEMONSTRATED weakness. A complex key will stop a bruteforce attack in its tracks. To be clear, I'm not trying to disagree with here, but, I feel it's safe to say, the majority (80%? Maybe I'm being too generous) of WPA keys are not complex. Maybe the comments should be pointing to the end-users' weak password complexity, instead of outright saying WPA is weak / WPA can be cracked with ease.
Given that, the video is indeed misleading to prove it's own point.
I don't think that app would fare too well against a password in 3 different languages with unique slang and random numbers.

Hmm, so you're going to spend $7k+ ($1500 per GPU, $500 for a Mobo, $500 for other components) on a rig so you can crack WPA passwords on people's $50 internet connections? Come again? |
