Mathy Vanhoef, a researcher from the University of Leuven (KU Leuven), has discovered a severe flaw in the Wi-Fi Protected Access II (WPA2) protocol that secures all modern protected Wi-Fi networks.
WPA2 is the security protocol for Wi-Fi. It replaced WEP, which was hacked many years ago. While WEP is still supported by most wireless access points, WPA2 is now the recommended security measure.
