Wait... your neighbor had an ethernet port in their apartment that was shared in your apartment? That's not a home network, that's more like a MAN (or Metro Ethernet or something). That ethernet port in your apartment should 100% be treated as hostile if that's the case.
- subway 9y agoThe building has a shared ethernet fabric with a wireless uplink. With this configuration (and it isn't an uncommon configuration), anyone on the ethernet fabric can throw up a dhcp server and assign addresses/rutes to anyone else (or a number of other attacks). DOCSIS has had similar issues in the past -- folks on the same node could directly pass frames between each other, and in some situations you could sniff your neighbors traffic. My point was that whether you're at home or out and about, you shouldn't trust the "quality" of your internet connection, and should focus on having end to end encryption with whatever service you're attempting to communicate with.
