There was another #Pittsburgh#apartment and it’s like everyone’s apartment just has an Ethernet cable that runs to some sort of router/switch that somehow provides everyone Ethernet. No idea how that works or if that’s how big apartments do it now, or how safe/secure it is.
Anything like that would be run through a NAT router where the uplink side is considered “Wild West” or whatnot.
It’s getting so hard for me to keep up with this stuff.
I guess it depends on if all the apartments individually are on VLANs.
Adding in a router would add double-NAT but assuming no DMZ or port forwarding, it should isolate it decently. (I would probably only do banking stuff over cellular connection.)
I think a four-unit mom and pop has a much bigger risk of not using VLANs and instead SOHO crap than a couple hundred unit complex.
@feld Wow. If you could hop onto someone else’s LAN that way you could perform ARP attacks too, right?
Did you ever let anyone know?
Could you defend against that by having a NAT router with your own WiFi? They could connect into your VLAN, but there’d be absolutely nothing there. (They could still send WAN traffic posing as you which is also super bad.)
God I want to go back to the 28.8 modem. I never thought I’d ever say that.
