I wonder if governments have cracker units, for going after enemy countries in times of war, or times of cold-war? There are reports of North Korean hackers doing exactly that. The crackers in the article, (at least the non-malicious ones) could they join the army as a get-out-of-jail free card, or would that glamorize them? Are they ever rehabilitated?
