The Multics cookie monster
> created Elk Cloner as a prank in February 1982
Ahem, in the late 70's (possibly earlier, but that's when I first encountered it) there was a "daemon" running around on Multics systems. Briefly, if you became it's lucky victim, it would take over your console and type up
I wanna cookie
on your screen (yes, we did have VDUs back then). Typing "cookie" would get it to go away for a while. Telling it to 'koff would get your session terminated (logged out). From what I recall it was written in PL/1 and was only a couple of pages of lineprinter paper.
Oh and BTW:

It's not just the O/S that needs to be secure (and there are secure ones around), but the way it's used needs to be secure, too. That's the real problem
