DISCLAIMER A large cablenetwork company has been informed of this MISBEHAVIOUR and threatened to disconnect me. they would not think of a proper sollution : Purpose: A Hackers dream, work from your won PC with IP Addresses someone else owns: In short, Occupy IP Addresses someone else normally owns. Normal Broadband Cable networks either give out DHCP Addresses or a Fix Address or Address range. When doing a SNIF on the outbound iface a proper designed network should not broadcast ARP request not meant for the network on that end of the CableModem. Some Networks However are Weak Configurred and broadcast ARP for the entire shared medium through all Cable Modems attached to that Network. A smart hacker would setup the outbound iface to reply to all ARP requests it gets, therefor being able to take any IP Address that is broadcasted for. This makes folliwng possible: Dos. Hacking using Outhers Addresses Not to mention all other fun... any Comments on this ? -- --- Kind Regards Patrick Maartense (using Pine on a Text Console)
