Record Cyberattacks Target South Korean Military Amid North Korean Threats

In 2025, South Korea's military faced a record 18,951 cyberattack attempts, marking the highest level in five years. The majority of these attacks, 18,792, aimed to gain administrator access to military websites. The Cyber Operations Command attributed these sophisticated attacks to North Korea, which has reportedly enhanced its cyber capabilities. The South Korean government struggles to retain cybersecurity specialists, with 85% of commissioned officers from 2016 to 2019 opting for early discharge after their mandatory service. Recent efforts by North Korea to expand its cyber operations through the Reconnaissance General Bureau have raised concerns about the ongoing threat. The military's cybersecurity workforce challenges compound the risks posed by these escalating attacks.

Key Points: • South Korea's military recorded nearly 19,000 cyberattack attempts in 2025, the highest in five years. • Most attacks targeted administrator privileges on military websites, indicating advanced tactics. • 85% of cybersecurity officers commissioned between 2016 and 2019 left the military after service.
