KAIST (President Kwang Hyung Lee) announced on the 23rd of November that HyungSeok Han (Ph.D. alumnus from the School of Computing) and Insu Yun (B.S. alumnus, currently Associate Professor in the School of Electrical Engineering) donated 150 million KRW from the prize money won by Team Atlanta, which took first place in the world’s largest AI security competition, the “AI Cyber Challenge (AIxCC),” organized by the U.S. Defense Advanced Research Projects Agency (DARPA).

The AIxCC final round was held this August in Las Vegas, where Team Atlanta—a joint team consisting of researchers from Samsung Research, KAIST, POSTECH, and Georgia Tech—secured the top prize. AIxCC is the world’s largest AI security competition, with a total prize pool of 29.5 million USD (approx. 41 billion KRW). Over the past two years, security companies and research teams worldwide have competed with AI-based security technologies, showcasing state-of-the-art capabilities.

A total of 91 teams registered for the competition, 31 teams participated in the qualifiers, and 7 teams advanced to the finals. Team Atlanta won the first-place prize of 4 million USD (approx. 5.8 billion KRW), securing victory with an overwhelming margin comparable to the combined scores of the second- and third-place teams. The team also swept major titles such as “Most Vulnerabilities Identified” and “Highest Scoring Team,” demonstrating exceptional technical superiority.

HyungSeok Han earned his B.S. (2017) and Ph.D. (2023) from the KAIST School of Computing, then worked as a postdoctoral researcher at Georgia Tech before joining Samsung Research America where he currently works. In the competition, he served as the team leader for the development of the automatic vulnerability detection system and oversaw system integration and infrastructure, making major contributions.

Insu Yun received his B.S. (2015) from the KAIST School of Computing and his Ph.D. (2020) from Georgia Tech. Since 2021, he has been a faculty member in the KAIST School of Electrical Engineering. In this competition, he led the patch development team and played a central role in enhancing overall system completeness.

The two researchers decided to donate 150 million KRW of their prize money to the School of Computing and the School of Electrical Engineering. The School of Computing will use the donation as a scholarship fund, while the School of Electrical Engineering will apply it toward student education and research support, in line with the spirit of the donation.

Alumnus HyungSeok Han remarked, “Building a system in which AI autonomously discovers vulnerabilities and even generates patches has long been a dream of mine and an important milestone in the security field. I’m grateful to have achieved meaningful results together with KAIST alumni, and I hope KAIST will continue to exert a positive influence on global technological advancement.”

Professor Insu Yun stated, “I’m truly grateful to every member of Team Atlanta. In particular, I want to thank Professor Taesoo Kim, our overall team leader and advisor, the students in our lab who worked tirelessly, and Dr. HyungSeok Han, who joined me in making this meaningful contribution.”

KAIST President Kwang Hyung Lee commented, “I deeply thank our alumni for achieving outstanding results on the world stage of technological competition and for generously giving back to their alma mater. This achievement demonstrates KAIST’s educational and research excellence and stands as meaningful evidence of the global competitiveness of Korea’s AI and security technologies. KAIST will continue to lead advanced AI and security innovation and do its utmost to nurture creative talent who will contribute to humanity and society.”

To encourage further alumni contributions, the KAIST Development Foundation is operating the Team KAIST (https://giving.kaist.ac.kr/ko/sub01/sub0103_1.php) campaign to promote alumni participation.
