As we know, the WPA2 security protocol is using to protect and security communications Wi-Fi networks for many years, but the vulnerability affects all the most devices and operating system, included network devices, mobile devices,
Internet of Things (IoT) devices, Android, Apple, Windows, Linux, and more, if your devices support Wi-Fi, it most likely affected.

From the researcher’s report said “Concretely, attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on. The attack works against all modern protected Wi-Fi networks. Depending on the network configuration, it is also possible to inject and manipulate data. For example, an attacker might be able to inject ransomware or other malware into websites”

For Microsoft customers who have enabled Windows Update and applied security updates from Oct. 10 are automatically protected from a Wi-Fi security flaw nicknamed “KRACK,” if not, please install security patches asap.

For other vendors, please get security patches or firmware from their websites and install them.

Hope you enjoy this post.
