WPA Encryption Cracked

Wi-Fi Protected Access (WPA) encryption for wireless connections is considered a better and safer alternative than the older Wired Equivalent Privacy (WEP) standard that was cracked a long time ago. Security professionals may have to rethink their stance on WPA as researchers have developed a way to partially crack the encryption used. By 'partially', the researchers said they developed a way to intercept and read the data being sent from the router to a laptop computer but they have not yet been able to crack the encryption used to send the data from the computer to the router. The researchers, Erik Tews and Martin Beck, found a way to crack the Temporal Key Integrity Protocol (TKIP) key fairly quickly without using a dictionary attack. By tricking the router to send them a large amount of data, the research team developed what they call a “mathematical breakthrough” to crack the key in under 15 minutes. The newer WPA2 standard is believed to be safe from this method of attack.

As a side note WPA was crackable before this hack was discovered but the time it took was so long a successful attack on WPA was not practical. Now however with this breakthrough hacking WPA is more practical due to being able to crack it almost as fast as cracking WEP.

OK they got TKIP. I run WPA2 AES, I figure people like us will go for the highest security possible. In fact the last I ran a router setup program it defaulted to AES, so the rest of the world has some protection IMHO. @ Nerm, yeah, I remember maximum pc saying something like 'it would take a stadium full of QX6600s' and a bunch of time to break wpa. Well it was only a matter of time. Also, I use this to generate network keys.
