North Korea’s “fast-developing tech abilities” could be helping it scale up its raids on financial sector targets like international crypto exchanges, say South Korean observers. Experts have spoken out after a report from the American armed forces concluded that several thousands of North Korean operatives are active worldwide, conducting hacks and raids on global crypto exchanges and other financial institutions. Janet Cho, an IT journalist based in the South Korean capital, told [Cryptonews.com](http://Cryptonews.com) that security experts based in the country have reported a “near-constant” flow of “spear-phishing attack attempts” they say originate from north of the Demilitarized Zone.
