      Am I missing something, or is the Android/wpa_supplicant "all zero key" KRACK bug mostly FUD? Surely wrong key = traffic can't flow.

      Sure, maybe if you have an app spamming UDP or something, but in practice you're going to get a bunch of TCP retransmits and then death, no?

      I'm sure you can target some protocols to leak secrets, but this sounds *way* more invasive&impractical than the implied "it's cleartext".

      Doesn't help you MITM an intranet, which is the biggest threat of these WiFI attacks. Public internet use should already be untrusted.

      what protocol would you MiTM in the intranet disconnected from the public internet?

      Anything. People (sadly) still believe in network security. Plenty of businesses give you juicy stuff if you can get on their WiFi.
