A researcher has released details on vulnerabilities in the Wi-Fi Protected Access II (WPA2) protocol, which he calls KRACK.

Attacks taking advantage of the issues that makeup KRACK will work against all modern protected Wi-Fi networks. To put it another way, if a given device supports Wi-Fi it is likely impacted by the KRACK vulnerabilities.

This is because the weaknesses are in the Wi-Fi standard itself, not in a given product or implementation.
