KRACK affects the core WPA2 protocol (targeting the 4-way handshake) against all modern protected WiFi networks. HTTPS is not necessarily immune, depending on configuration settings. 

It seems hackers need to be near their targets, basically anything nearby with a Wi-Fi connection is fair game, so your devices are vulnerable. 

Enterprise and government --- as well as private, at home --- WIFI networks are vulnerable until proper security patches and updates are made available and applied.
