1st year at Uni. Year is 1993. 286 running DOS on top of Novel Netware and booting from network off a 386 behemoth that need it to run 1st. So this guy was the sysadmin, a freshly minted assistant which had the bad habit of copying our sources and see if anything interesting is in it. Therefor I wrote a piece of code called Super.exe with nice graphics and a lot of bling bling that had inside a virus which when run from a normal user (like ours) did nothing but when was run from a Supervisor (Novel's name for Administrator) account would create another user called Hypervisor with blank password. I created the .exe, erased the sources and let it sit on my account and went home. Next morning I tried the Hypervisor account and what do you know! I got in. Used for next 3 years to give my normal user more space when I need it and to do creepy stuff to said assistant when he was pissing me off. Poor sod never knew, always suspected bugs and viruses. I told him 5 years after that, when we met by chance at a beer with common friends. His eyes opened wide and exclaimed: "So it was you!!? I never suspected you". Fun times.
