On Monday, it was announced publicly that Wi-Fi security, specifically the WPA2 standard, was essentially broken. The culprit is a bug named KRACK (Key Reinstallation Attack) which takes advantage of fundamental flaws in how WPA2 operates, and has exposed many shortcomings in how the industry responds to such attacks as well. WPA2 (Wi-Fi Protected Access II) is hugely prevalent, as it is the current generation of authentication used on wireless networks. That means that almost every wireless device could be affected by KRACK, as most devices use WPA2. This includes everything from laptops and phones to routers and IoT (Internet of Things)/Smart devices.
