Next I installed a hacked version of "telnetd" that would capture and store the password of anyone who logged in to the Novell gateway machine. As I was getting myself established on Novell’s network, I saw that two other users were logged in and active. If they happened to notice that somebody else was logged in from a remote location, they would immediately know that the company was being hacked. So I took steps that made me invisible: if any system administrator called up a list of everyone who was on the system at that time, I wouldn’t show up.
