Assuming Comcast has a bandwidth cap, by spoofing real MAC addresses he's basically stealing other users' bandwidth.
But then again, people steal wifi all the time.
- akamaka 17y agoWhen it comes to wifi, I'd drawn the line between stealing and innocent "borrowing" at the point when someone actually goes through the trouble of running a WEP password cracker, which is akin to what happened in this case.
- blasdel 17y agoThere's also no reason to spoof the MAC addresses of real subscribers. If your modem's external MAC isn't in Comcast's (global!) subscriber table, they give your modem a "walledgarden" default configuration file that causes it to reset frequently, and a poisoned DHCP DNS that directs all queries to their "Subscribe Now!" webserver. Some of the European ISPs have countermeasures that rotate the names of the configs frequently, but Comcast doesn't do that -- if you've modified your modem, all you have to do is have your modem ask for a different config file (the names of which it will sniff from your neighbors), and set a different DNS server on the modem's immediate clients.
