South Korea's Cyber Operations Command is participating in a US-led multinational cyber exercise this week, the Ministry of National Defence in Seoul announced on Monday.

Seven personnel from the command are taking part in the five-day Cyber Flag exercise, which began in Virginia, United States. This marks South Korea's fourth participation in the exercise since first joining in 2022.

Launched in 2011, Cyber Flag is an annual exercise designed to enhance cooperation between the United States and its allies, particularly the Five Eyes intelligence alliance, which includes Australia, Canada, New Zealand, the United Kingdom, and the United States. The exercise provides a platform for partner nations to strengthen their collective ability to detect, respond to, and mitigate cyber threats through practical, scenario-based training.

According to the Ministry, Cyber Flag, together with bilateral exercises between South Korean and US cyber commands and the exchange of personnel and technologies, is expected to further advance cooperation between the two countries in the cyber domain.

The Cyber Flag exercise involves the Five Eyes intelligence alliance-comprising the United States, United Kingdom, Australia, Canada, and New Zealand-alongside other partner countries. The program focuses on enhancing collective capabilities to counter cyber threats through practical training.
