Define "that many"...

It's not about the total number -- it's simply about the fact that 
there really are some, and we know that here some == quite a few more 
than one.  Better to think of it in terms of a proportion though,   
then allow that the law of large numbers kicks in _on both the 
attackers' and victims' sides of the equation_.  If the potential 
attackers can run their probes from a botnet then they reduce their own 
workload significantly are not even risking discovery or any real 
"loss" if they tracked/shut-down as it is all but guaranteed that all 
they will lose is a bot or two in the odd case where someone will care 
enough to try to track down "the attacker".  And if the available 
victims are, say 0.00015% of all machines, scanning a few million 
machines gets you plenty more new victims.

And that's not even considering that some machines may be more 
worthwhile cracking than others...
