Security Alert! Your Wi-Fi is affected by KRACK!
In the last months, a serious security issue for Wi-Fi networks and the devices that use them has been discovered. WPA2, which is how all modern Wi-Fi networks are secured, has found to have weaknesses. Attackers can exploit those within range of a victim using key reinstallation attacks (KRACKs). Discovered by researcher Mathy Vanhoef, KRACK exploits limitations in implementations of the handshake processing in the 802.11 protocol.
