There are several ways to crack a wireless network’s security. The weakest, WEP, can be easily cracked using customized Linux software, but until today, Wi-Fi Protected Access (or WPA) had been considered secure. Not any more. Researchers have announced that they’ve developed a way to partially crack the encryption standard, but I warn you, it’s not easy.
The researchers, Erik Tews and Martin Beck, have found a way to break the Temporary Key Integrity Protocol (or TKIP) in as little as 15-12 minutes. They have not yet, however, managed to crack the encryption keys used to secure the data that travels from the PC to the router.
