The Evolution of North Korean Hacking Techniques

North Korean hacking groups, particularly Lazarus, have transitioned from simple phishing methods to more sophisticated approaches involving zero-day exploits. This evolution was triggered by incidents where they employed advanced technical capabilities to target sensitive sectors like cryptocurrency and aerospace, indicating a significant investment in training and development. Unlike earlier operations that relied heavily on phishing tactics, these recent activities highlight a strategic shift towards technical proficiency and resourcefulness in hacking. This change underscores the importance of building in-house expertise rather than solely relying on third-party vulnerabilities that may come at a high cost.
