So you might ask who is winning this war? Well that's a tough answer to give. See many attacks do not get publicized. In fact some can go years before even a hint is made. That is the case with Stuxnet on Iran, who didn't admit to these attacks for several years. Recently the NY Times discovered hackers from China were responsible for hacking their website. Without knowledge of how successful the attacks were, we can not gage the scope of the damage, or the causalities. So we have no idea how this war goes. But it is being fought, and we should all be aware that it is occurring.
The day has come when a few 0's and 1's can bring down a nuclear program.
