From Silicon Labs: KRACK WPA2 Encryption Protocol Vulnerability
There has been significant press coverage regarding the KRACK attack on the WPA2 protocol used in most modern Wi-Fi systems. With the attack, the security of WPA2 becomes equivalent of using an open, insecure Wi-Fi network. Any service using secure protocols at higher level, such as HTTPS, TLS etc. are still secure.
We are working on patches for our Wi-Fi products.
In the meantime, the mitigation is to secure the implementations using secure application level protocols, such as HTTPS, TLS etc. This should not only be done due to KRACK, but also because that would protect against open Wi-Fi networks, spoofed access points, or monitoring from ISPs or governments. So all systems should be secured at the application levels regardless of KRACK.
