True, Zombies are a way that your terminal alone is used in exploits, even if you have no Highly sought after info on your computer. You could be liable for someone else using it as a hackig exploit.

Also if you are using a cable connection...think of it as a single phone line in your house with 6 phones hooked up to it. Any one can pick up and listen in or talk. It is just as easy...you share everything on a cable connection, VERY insecure
