https://arstechnica.com/information-technology/2017/10/how-the-krack-attack-destroys-nearly-all-wi-fi-security/ >A paper by two Belgian researchers has cast more light on the vulnerabilities discovered in the Wi-Fi Protected Access II (WPA2) implementations on most, if not all, wireless networking devices that use the protocol. Dubbed "KRACK" (Key Reinstallation AttaCK), the attack "abuses design or implementation flaws in cryptographic protocols to reinstall an already-in-use key," wrote Mathy Vanhoef and Frank Piessens of the Katholieke Universiteit Leuven (KU Leuven) in the paper, released today.
