System administrator Oryell appeared to use the host blackhole as her personal workstation. I figured she would eventually want root privileges to perform an administrative task and would use the Unix switch user command, "su," so I set up a way of capturing the root password when she did. (For the technical reader: using the source code I had obtained from Sun Microsystems, I added some additional code to the "su" program and recompiled it so when she su’ed to root, it would secretly log her password to a file hidden on her workstation.)
