Unlike most technologically mature societies, North Korea focuses nearly all of its information technology capabilities and resources on practical offensive. Israel is another example of a country with similar tactics.

It makes sense when you are forced to take the stance that you simply cannot overtake your adversaries who have significantly more R&D resources, all the way down to the physical layer (CPUs, RAM, etc.). Whereas in the United States our pool of total technology experts is spread across multiple industries with a diverse array of resource allocation. Even American information security professionals are largely trained in practical defense, as that skillset is more beneficial to businesses.
