WPA Cracking in the Cloud
It’s a service:
The mechanism used involves captured network traffic, which is uploaded to the WPA Cracker service and subjected to an intensive brute force cracking effort. As advertised on the site, what would be a five-day task on a dual-core PC is reduced to a job of about twenty minutes on average. For the more “premium” price of $35, you can get the job done in about half the time. Because it is a dictionary attack using a predefined 135-million-word list, there is no guarantee that you will crack the WPA key, but such an extensive dictionary attack should be sufficient for any but the most specialized penetration testing purposes.
It gets even better. If you try the standard 135-million-word dictionary and do not crack the WPA encryption on your target network, there is an extended dictionary that contains an additional 284 million words. In short, serious brute force wireless network encryption cracking has become a retail commodity.
In related news, there might be a man-in-the-middle attack possible against the WPA2 protocol. Man-in-the-middle attacks are potentially serious, but it depends on the details—and they’re not available yet.
EDITED TO ADD (8/8): Details about the MITM attack.
