IT Help Desk News It was announced on Monday, October 16, 2017 that the globally used WPA2 Wi-Fi security protocol has a vulnerability. This protocol is the most commonly used security protocol used by Wi-Fi networks around the world. The attack targets (and breaks) the unique encryption keys for that session. The attack is called KRACK, (Key Reinstallation Attack). The vulnerability impacts just about any device that uses WPA2 to connect to a Wi-Fi network, which today is about all of them. This does not impact just smartphones, laptops and tablets, rather any device that connects to a Wi-Fi network. The best way to make sure you are protected against this vulnerability is to make sure your devices that connect to Wi-Fi have the latest updates for that device and the automatic update feature is turned on (Spitzner, Lance – SANS Institute: “KRACK Attack – What to Communicate”). Vendors are currently developing patches for this attack. Several, such as Microsoft, have already released patches.
ZDNET is a technology news outlet that has a great list of the patch status from the biggest vendors available here:
