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. 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. KRACK (short for, uh, Key Reinstallation AttaCK) targets the third step in a four-way authentication "handshake" performed when your Wi-Fi client device attempts to connect to a protected Wi-Fi network.
