Professor Yoon, MyungKeun and students Hyun-Ki Son, Seung-Ryeol Baek, and Yoon-Ho Lee from the Information Security Research Lab, Software Convergence College, Kookmin University (President Jeong Seung-ryul) Choi Young-rak, and Jang Seung-hyun from the Information Security Research Laboratory at the Software Convergence College of Kookmin University won the Best Paper Award (Ministry of Science and ICT Award) at the “2025 Summer Academic Conference of the Korean Information Security Society” held on June 24-25, 2025, demonstrating their outstanding research capabilities.

The National University of Korea's Information Security Research Team presented their research titled “Real-time Detection of BPF Backdoor Magic Packets,” analyzing recent incidents of SIM card information leaks caused by BPF backdoors at major domestic telecommunications companies and proposing technical countermeasures to prevent such severe security incidents from recurring.

Notably, the research overcame the limitations of existing signature-based detection methods and developed a technology capable of real-time detection of BPF backdoors and their variants based on network behavior. Its effectiveness was validated through testing in actual traffic environments, earning high praise for both its academic and industrial value. This research was conducted with support from the Ministry of Science and ICT (MSIT) (National Research Foundation of Korea RS-2023-NR076564: “Generative Security Research for Zero-Day Defense,” Information and Communications Planning and Evaluation Institute RS-2023-00236032, “Development of Network Behavior-Based Security Monitoring Technology for Encryption Cyber Threats in ICT Convergence Public Services and Infrastructure”).

Meanwhile, the National University of Korea's Information Security Research Team is currently researching and developing next-generation artificial intelligence security technology capable of detecting abnormal behavior or identifying applications even in encrypted traffic environments.
