One only needs to look at the recent issue with hacking cars to see that it is quite possible. A single bomb, short of a nuke, would do far less damage than a virus attacking certain vehicles. The real issue is the effort needed to acquire the bomb/build the virus. Bombs seem to still have a far lower startup cost, so while you may get less bang for your dollar, they are more popular. Is it popularity or damage/$ that determines what is more dangerous?
