At CES this week, the Wi-Fi Alliance announced WPA3, the newest security protocol for Wi-Fi devices. WPA3 includes four new security capabilities and is the most significant upgrade to Wi-Fi security since 2004.
A serious flaw in the wireless protocol that secures all modern protected Wi-Fi networks has been discovered. If your device supports Wi-Fi, it is most likely affected. This feasible attack, dubbed KRACK, could abuse design or implementation flaws in the Wi-Fi standard, not some specific hardware.
