In this example, the intruder was connected to a corporate LAN and did a lot of work with another researcher on a different LAN. The backbone was set up in such a way that it took five hops and a 56-kbps line to get to the other research machines. By capturing routing information and having enough knowledge to change the routing metric information, the intruder altered the path so that his access became seemingly better through a backdoor connection. However, this modification resulted in all traffic from the intruder’s LAN being rerouted, saturating the backdoor link, and causing much of.
