Kali Linux (VirtualBox) instructions for testing any Wi-Fi device against WPA2 Key Reinstallation Attack (KRACK Attack)

The following article demonstrates the process of testing any Wi-Fi capable device against a key reinstallation attack. I’ll demonstrate the processes of executing the test using Kali Linux installed in the VirtualBox on a Windows machine. Then I’ll illustrate the process of testing recently patched Windows 10 as well as testing unpatched Android 7.0 mobile phone against the key Reinstallation Attack. This article also explores a newly discovered vulnerability of WPA2 named KRACK Attack (key reinstallation attack) in little more detail, as it’s one of the biggest vulnerabilities found in WPA2 to this day (patched only by a handful operating systems and Wi-Fi product manufacturers).
