Pretty Fly for a Wi Fi

• gruez 2y ago
  That's actually bad. iOS shows a "privacy warning" if you're connected to a wifi hotspot with a "common name". Presumably that's because if you have something a network with a common name saved (eg. "dlink"), your phone would try to connect to it everywhere you go, exposing your mac address.

    It was what I thought of when you said "stick out" - because I never see it, and it catches my attention each time. (Your regions may vary!)

    > your phone would try to connect to it everywhere you go Emphasis on "try", provided the original network wasn't some kind of totally unsecured open one. (And nobody would do that nowadays, right?... Right?) IANANetworkEngineer, but from what I can find about "Evil Twin" WiFi attacks, your device ought to remember and reuse the security info from the legitimate AP. Even if the hacker mimics the SSID and MAC, they probably won't have the other secrets needed to finish tricking your device into finalizing the connection. > exposing your mac address This can be avoided if your device is set to randomize its MAC on each connection to an SSID or that one in particular. However there are some networks where that is undesirable, like a home network that does some assigned IPs and port-forwarding across NAT, etc.

      >This can be avoided if your device is set to randomize its MAC on each connection to an SSID or that one in particular. AFAIK only grapheneOS offers per-connection mac randomization. Windows comes close with "change daily". Regular Android has a developer setting that enables it for all networks, which causes issues like you mentioned.

        I know regular Android since version 10 has a standard randomization feature, but as you say it's not as strict as per individual connection attempt, just per recognized SSID.
