Huge security flaw leaves Wi-Fi devices wide open to hackers

There's a hole in Wi-Fi security, and it affects the vast majority of Wi-Fi devices and networks. That very likely means your phone, your home wireless network, your wireless network at work -- everything. Belgian security researcher Mathy Vanhoef from the imec-DistriNet research group at the KU Leuven university has discovered a vulnerability in the WPA2 security protocol, used by nearly every Wi-Fi device out there. It allows an attacker to remotely extract decrypted data from a protected Wi-Fi network without knowing the password.
