Having said *that*, a salutary tale. I'm on a cablemodem connection and some time ago I had a letter from ntl (as it was) claiming I had been identified as the source of spam being sent out. As I knew conclusively they were wrong I rang them to query this, ending up chatting to a Senior Tech. He checked into the accounts and found *three* IP addresses logged against the MAC address for my cablemodem. Someone had spoofed my MAC address[1] - something I suspect is harder than spoofing an IP address. Given this incident I'm curious how the complainant (or the ISP for that matter) could conclusively prove that the customer - the accused - was the only person capable of using that IP address.
You'd be surprised. I gather cable modem hacking is common place.
[1] In the end ntl supplied me with a new modem, despite the fact I had bought the old one - they paid me the cost price.
You bought your own modem?Hmmm, I got one with the service when I was with NTL. Got an old Telewest one in the loft which they never collected from last time (they picked the TV box up but not the modem) although now I have a new one for my current Virgin service. I presume if I cancel or upgrade either the TV service or modem they'll swap them out anyway (I'm looking at getting the new Virgin V HD box in April at 50 quid one off fee and free self-install).
