Summary of WPA2 KRACK vulnerabilities
According to security researcher Mathy Vanhoef of Leuvern University, the “WPA2 Key Reinstallation Vulnerabilities (KRACK) Explained” vulnerability can render WPA2’s powerful encryption function obsolete. As a sort of Man-in-the-Middle (MITM) attack, the KRACK vulnerability can intercept encrypted data between an AP and a station without having to access the AP. It allows theft of all information traversing a network such as credit card information, passwords, chatting messages, and e-mail.
