       my roommate got an LTE modem and the way this thing works is pure nonsense. It shows up as a USB ethernet connection. That's not too weird, it's basically a network thing, right?but no, it acts like an ethernet device, and if it can't get an LTE connection, it tells the PC that there's another host on that ethernet running a webserver so it can redirect your browser to that site

       @foone This is what I've seen a bunch of actual cable modems do, for what it's worth, although it's a little less weird because they're using "real" Ethernet.

       @foone AFAIK many Sierra Wireless LTE modems can also be switched into what's called "DirectIP" mode which will just present a CDC USB Ethernet device to your OS and hand out a WWAN via DHCP. Though I doubt those modems do any weird internal HTTP redirects!

       @foone sounds like a ZTE stick I once had. It was basically a router. I mean the stick even had a wifi ap iirc.

       @foone yeah that sounds about normal for Huawei kit. The real kicker is that every single one of them, even different models, is identical at the USB layer - same USB VID:PID, same USB serial, same product name, AND SAME USB-CDC ETHERNET MAC ADDRESS

       @foone then you hack into that host and see that behind that host is a whole network with load balancers and firewalls.Getting through the firewall was hard, but finally you acess the WAN and see millions of hosts with huge websites and networks.It's a whole world, tucked away in that small LTE modem.Chapter 3: exploring the network

       @foone These devices are the consumer version of most enterprise middleboxes: made by people who should not touch any network device ever and possibly not any other kind of computer either.
