        Kr00k affects devices using Broadcom and Cypress Wi-Fi chips.

        Today, at the RSA 2020 security conference in San Francisco, security researchers from Slovak antivirus company ESET will present details about a new vulnerability that impacts WiFi communications.

        Named Kr00k, this bug can be exploited by an attacker to intercept and decrypt some type of WiFi network traffic (relying on WPA2 connections).

        According to ESET, Kr00k affects all WiFi-capable devices running on Broadcom and Cypress Wi-Fi chips. These are two of the world’s most popular WiFi chipsets, and they are included in almost everything, from laptops to smartphones, and from access points to smart speakers and other IoT devices.

        Apple has patched the exploit with the iOS 13.2 and the macOS 10.15.1 update that was released back in October 2019.

        That’s good – for Apple, what about everyone else?  (Rhetorical question).

        There is also a Cisco related article on this subject via borncity that concludes:

        What’s silly: There are no firmware updates and no workarounds to fix this vulnerability. Cisco intends to release software updates that address this vulnerability.
