WPA Wi-Fi Encryption Partially Cracked, WPA 2 Finds New Fans

Wireless security is somewhat important, especially if you want the riff-raff of your network and keeping their prying eyes from the personal information you transmit wirelessly. WPA TKIP has served as a more robust encryption scheme for many home routers (as WEP is completely useless) but it seems researchers have spoiled all of the fun and found a vulnerability in it. ITworld has more details:

The attack, described as the first practical attack on WPA, will be discussed at the PacSec conference in Tokyo next week. There, researcher Erik Tews will show how he was able to crack WPA encryption, in order to read data being sent from a router to a laptop computer. The attack could also be used to send bogus information to a client connected to the router.

To do this, Tews and his co-researcher Martin Beck found a way to break the Temporal Key Integrity Protocol (TKIP) key, used by WPA, in a relatively short amount of time: 12 to 15 minutes, according to Dragos Ruiu, the PacSec conference’s organizer.

They have not, however, managed to crack the encryption keys used to secure data that goes from the PC to the router in this particular attack.

Migrate on over to WPA AES or WPA2 at your leisure.
