The Korea Internet & Security Agency (KISA) said on Nov. 9 that Team BoB, made up of graduates and trainees from the Best of the Best (BoB) programme, won Taiwan's AEGIS CTF international invitational.

AEGIS CTF is a cybersecurity competition led by Taiwan's state-run research institute, the National Chung-Shan Institute of Science and Technology (NCSIST), among others. This year it was held as an international invitational for white-hat hackers worldwide from Nov. 7 to 8 at National Cheng Kung University.

A total of 16 teams participated, including 10 teams from Taiwan, the previous year's winning team from Taiwan, and 5 international invitational teams.

International teams included South Korea's Team BoB; MMM, a U.S.-South Korea-Canada joint team that won DEFCON CTF in 2024 and 2025; and Water Paddler, a team that is part of Blue Water, which won in 2026. Lv1x of Malaysia and Dojo of Thailand also took part.

Teams tackled tasks including AI-based threat detection, vulnerability analysis, real-time defense, and security for AI and machine-learning systems, KISA said.

Jung-hoon Shin (신정훈), lead mentor for the vulnerability analysis track at the BoB programme, said: "With the advancement of generative AI, the security research environment is changing rapidly, but verifying the results AI presents and discovering new problems still depends on the capabilities of security experts." He added: "This competition was a meaningful opportunity for BoB trainees to prove on the international stage the technical skills and problem-solving abilities they have built up."
