The U.S. government’s cybersecurity chief resigned with a day’s notice. I can understand his frustration; the position had no power and could only suggest, plead, and cheerlead.
North Korea had over 500 trained cyberwarriors, according to the South Korean Defense Ministry. Maybe this is true, and maybe it’s just propaganda—from either the North or the South. Although certainly any smart military will train people in the art of attacking enemy computer networks.
