Un poco de teoría sobre nuevos ataques a WPA, para ir leyendo:

A Practical Message Falsification Attack on WPA (http://jwis2009.nsysu.edu.tw/location/paper/A%20Practical%20Message%20Falsification%20Attack%20on%20WPA.pdf)

Conclusion
This paper has proposed a practical message falsification attack on any WPA implementation. Our attack is a method that applies the Beck-Tews attack to the MITM attack, and can falsify an encrypted short packet (e.g. ARP packet).

We have given a strategy for the MITM attack and the method for reducing the execution time of the attack. As a result, the execution time of our attack becomes about one minute in the best case. Therefore, our attack can execute on any WPA implementation, practically.

The future works are the demonstration experiment for our attack and the evaluation of the detailed execution time of our attack.

Parece ser que se ha montado un revuelo con la investigación de los japoneses:

New attack cracks common Wi-Fi encryption in a minute (http://www.networkworld.com/news/2009/082709-new-attack-cracks-common-wi-fi.html)

Esperaremos al día 25 a ver que pasa.
