This report aims to present the latest research findings on APT groups and contribute to the continuous improvement of cybersecurity defense capabilities. Our objective is to move from the unknown to the known, from visibility to comprehensive monitoring, and from monitoring to full-scale response and mitigation, thereby neutralizing APT threats at their earliest stages. By increasing threat groups’ operational costs, strengthening deterrence, enhancing cyber resilience, and improving rapid response capabilities, we strive to contribute to maintaining security and stability of global society in cyberspace.
