I mean Worm not Virus

It was successful, because it was a relatively novel approach of exploiting a very common vulnerability in colossal quantities in hopes that if it infects enough Windows machines, some of them would be the ones in contact with the PLCs of the centrifuges used in uranium depletion, or enrichment, or whatever they were using to develop their nuclear weaponry.
It’s said that at one point over half of all Iranian Windows machines were infected. The worm would then keep infecting all flash drives the computer interfaces with, hoping to get transported to a matching PLC, where it would lay in wait for a scheduled delayed execution.
That is it’s last “advantage” – since it didn’t mess up the centrifuges as soon as it infected them, it was much harder to spot. It’s almost certain that if it took them out one by one, they would have stopped the spread much sooner.
