South Korea’s ‘Cyber Shield’ Beats NATO and Allies; Cyber Operations Command Makes History with Five Consecutive International Competition Wins

[Financial News] As the paradigm of modern warfare rapidly shifts beyond physical clashes centered on weapons systems toward hybrid warfare involving the tampering with and theft of network infrastructure and critical military technologies, South Korea’s military has once again demonstrated cyber operational capabilities among the world’s best. Amid North Korea’s asymmetric cyber offensive, which threatens the security landscape of the Korean Peninsula by escalating cryptocurrency theft and the theft of defense-industry technology, the Cyber Operations Command, which oversees the South Korean military’s cyber security, achieved the historic feat of winning an international competition for the fifth consecutive year, competing against NATO member states and major allied countries.■NATO Member States and Partner Countries Face Off, Proving the ‘Cyber Shield’ Is Among the World’s BestAccording to the Cyber Operations Command on the 2nd, it took first place at the awards ceremony for the international cyber competition ‘CyberNet 2026’ (hereafter, CyberNet), held on the morning of the 30th of last month (local time) in Oldebroek, the Netherlands.
The Netherlands’ Cyber Command (DCC) has hosted CyberNet annually since 2018. It is one of the world’s most prestigious military cyber competitions, drawing large numbers of NATO member states and key partner countries to compete in national-level cyber resilience and operational capabilities. This year’s competition, held from the 26th to the 29th of last month, brought together elite cyber specialists from nine countries, including South Korea, Germany, France, Japan, Poland and Estonia. They engaged in intense offensive and defensive operations, carrying out sophisticated cyberattacks and defenses in real time.
Displaying its outstanding capabilities amid the competition’s intense technical rivalry, the South Korean military finished first and claimed the title. After a close contest, Poland took second place, followed by Estonia, home to NATO’s Cyber Defence Centre, in third.■The Secret Behind the Record Fifth Straight Win: Accumulated Know-How and Active Offensive and Defensive Techniques Combining AIThe military significance of this victory lies in the fact that it was not a one-off achievement but the result of systematic force development. After making its mark on the international stage by finishing runner-up in its first appearance in 2021, the Cyber Operations Command claimed its first victory the following year, in 2022. It has not relinquished the top spot since, setting a record with five consecutive wins through this year.
For this competition, the command carefully selected nine elite active-duty military personnel and civilian employees to form a task force (TF). They shared years of operational experience and know-how from competing, and developed their own tailored strategy. A decisive factor in the outcome was their intensive training in active cyberattack prevention and vulnerability detection using artificial intelligence (AI), reflecting the latest battlefield trends.
Cyber Operations Commander Brig. Gen. Bae Song-young of the Army said, “Winning the competition five times in a row has allowed us to once again demonstrate our military’s outstanding cyber operational capabilities to the world,” adding, “We will not rest on our laurels, but will continue to devote ourselves fully to strengthening our mission capabilities.”■North Korea’s Asymmetric Security Offensive, Including Bitcoin Hacks: Strengthening Protection of Defense Technology Is EssentialThe Defense Cyber Operations Command’s fifth consecutive win at an international competition is a significant security indicator, demonstrating that it has defended against increasingly sophisticated and large-scale asymmetric cyber threats originating from North Korea, as evidenced by operational data.
According to a weapons systems analysis report published by the U.S. Congressional Research Service (CRS) in August 2017 and a defense security report published in August 2023, North Korea’s Reconnaissance General Bureau (RGB) uses cryptocurrency theft as a key source of funding, covering about 40% of the budgets for weapons of mass destruction (WMD) and ballistic missile development, and prompting strategic concern in the United States.
According to ‘Analysis of Cryptocurrency Crime,’ released on November 1 last year by the global blockchain data platform Chainalysis, North Korea-linked groups stole $13.24 billion (about 18 trillion won) of the $22.34 billion in cumulative global losses from cryptocurrency hacks between 2021 and the end of October 2026, accounting for 59% of the total. The Federal Bureau of Investigation (FBI) also officially identified ‘TraderTraitor,’ a cyber group affiliated with North Korea’s Reconnaissance General Bureau, as being behind the recent $6.4 billion (about 8.5 trillion won) Binance hack, the largest in cryptocurrency history.
North Korea’s state-level hacking capabilities, which have devastated global cryptocurrency exchanges, pose a real threat to South Korea’s cutting-edge defense-industry data and military secrets. According to security indicators released by a South Korean intelligence agency in January 2024, state-backed hacking attempts targeting the country’s public sector averaged 1.62 million per day, with North Korean attacks reportedly accounting for 80%.
North Korean hacking groups immediately change their targets in response to orders from State Affairs Commission Chairman Kim Jong Un. In one instance, North Korea hacked South Korean shipbuilding companies and stole design blueprints shortly after an order to strengthen its naval power. Then, in October last year, immediately after an order to ramp up drone production, concrete indications reportedly emerged that it had illegally hacked key data on drone engines from related institutions at home and abroad. The relevant agency explained that the cyberattacks also employ an AI-enabled advanced persistent threat (APT) approach, persistently probing the South Korean military’s tactical data link networks and weapons-system networks.
With hostile forces committing their full national capabilities to all-out cyber warfare, strengthening cooperation with NATO member states and key partner countries and accelerating the South Korea-U.S. joint ‘Cyber Alliance’ exercise are seen as indispensable steps to safeguard the initiative in the asymmetric battlefield. The Defense Cyber Operations Command plans to maintain its technical and systematic defensive and deterrent capabilities against increasingly sophisticated global hacking provocations at the highest level through practical offensive and defensive exercises at home and abroad, including ‘White Hat 2026,’ and coordination on governance.
