I was going to make a trojan\rootkit and put it on the computers, which would keylog everything, then at the end of the year, enumerate all the printers each computer is connected to, and print out the logs like aids. Problem is spreading it, I thought of a couple methods(but they were fairly slow to spread). I have two more years and the remaining of this one to figure it out though.
I know how I can keep it on the computers though. It does acquire all the files from a network, however, the windows and other system files are kept and never touched. I plan to simply bind a quick virus installer to a system executable, then capow, it stays on the system.
