Flaw affecting devices with Broadcom and Cypress chips
Speaking at the RSA security conference, the ESET team claimed that Kr00k exists on all devices using Wi-Fi chips from Broadcom and Cypress and allows decryption of traffic only when they are relying on WPA2 connections.
Now, that might not seem concerning, but the thing is, these chips are used on billions of devices around the globe, starting from phones to IoT devices.
If, by any chance, your device manufacturer has not made the patch from Broadcom/Cypress available, we would recommend switching to the newer WPA3 Wi-Fi authentication protocol. This is because the bug in question only affects connections using WPA2-Personal or WPA2-Enterprise Wi-Fi security protocols.
