KRACK Wi-Fi attack threatens all networks: How to stay safe and what you need to know
A devastating flaw in Wi-Fi’s WPA security protocol makes it possible for attackers to eavesdrop on your data when you connect to Wi-Fi. Dubbed KRACK, the issue affects the Wi-Fi protocol itself—not specific products or implementations—and “works against all modern protected Wi-Fi networks,” according to Mathy Vanhoef, the researcher that discovered it. That means that if your device uses Wi-Fi, KRACK likely impacts it. Fortunately, major tech companies are moving quickly to patch the issue.
Read on for what you need to know about the KRACK Wi-Fi vulnerability, from how it works to how to best protect yourself against it. That starts with updating to iOS 11.1 and macOS 10.13.1 for Apple users, and installing the Android November security patch for Pixel and Nexus devices.
