While ordinary North Koreans face internet restrictions, they are simultaneously training large numbers of hackers. Reuters' November 6th report revealed specific details: 150 to 200 bright children are selected annually from middle school students, starting at age 11 or 12. The top performers, around age 17, enter top universities for further training, with only a very small percentage ultimately joining the military's cyberattack departments. What do they learn? Mathematics, computer science, cryptocurrency technology, and how to hack foreign hardware. The rewards are substantial: top performers reportedly receive US dollars and even housing in Pyongyang; a portion of the operational profits is also distributed to relevant military units. Therefore, the reality is a tightly integrated talent pipeline from selection and training to work and profit sharing, not just a few young people coding in rented rooms. Regarding the recent $6.3 billion Binance theft, the FBI pointed the finger at North Korea's TraderTraitor organization, which North Korea has publicly denied. Why target the crypto industry? Money moves quickly, crosses borders easily, and is difficult to trace. For these organizations, it's the lowest-cost ATM. In short: for some countries, cyberattacks are not just a crime, but an industry.
