MOV @-(PC), @-(PC)

Actually, it should be:

MOV -(PC), -(PC)

but, I hope you get the idea.

This is in PDP-11 MACRO-11 assembler. It is the simplest worm. The worm's
body consists out of single machine instruction MOV, which being executed
moves itself to the word before it and then sets the program counter to it.
So the worm advances the memory upward...
