North Korea’s Cyber Threat: Implications for European Security

October 13, 2025

Brussels – A recent report by the European Union Agency for Cybersecurity (ENISA) has revealed a concerning shift in the cyber threat landscape, identifying North Korea as the third most meaningful state-aligned threat actor targeting European Union member states, surpassing Iran in both activity and impact. The findings, published October 1, underscore an evolving geopolitical reality where Pyongyang’s digital offensive is becoming increasingly sophisticated and impactful.

Geopolitical Motivations Fueling North Korean cyber Activity

The ENISA Threat Landscape 2025 report details how cyber operations originating from North Korea are primarily driven by two strategic goals: financial gain and intelligence gathering. These activities directly align with the nation’s broader geopolitical ambitions,including navigating international sanctions and bolstering its military capabilities. Russia and China remain the most active state-sponsored threat actors, but North Korea’s rise is notably changing the dynamics.

Cybercrime as an Economic Lifeline for North korea

Decades of international sanctions, compounded by the economic fallout from the COVID-19 pandemic, have severely strained North Korea’s economy. To compensate, Pyongyang has increasingly turned to cybercrime to generate revenue. The nation’s hackers are actively targeting European companies, focusing on sectors like human resources, finance – especially cryptocurrency exchanges – and technology. Recent data from Chainalysis indicates that North Korean hackers stole over $2.17 billion in cryptocurrency during the first half of 2025 alone, with a substantial portion targeting European entities.This represents a 60% increase in cryptocurrency theft compared to the same period in 2024, according to a report by the Atlantic Council’s Digital Forensic Research Lab.

Did You Know? North Korea utilizes a network of illicit cryptocurrency mixers to launder stolen funds, obscuring their origin and making them more difficult to trace.

espionage Operations Targeting European Defense and Technology

Beyond financial motivations, North Korean hacking groups, notably Lazarus and Famous Chollima, are actively engaged in cyber espionage targeting key european industries. these include defense,aerospace,media,healthcare,energy,and government sectors. Analysts believe this intelligence gathering is focused on understanding the EU’s increasing defense spending, particularly the “ReArm Europe Plan/readiness 2030,” which aims to leverage 800 billion euros to bolster European defense capabilities. The recent NATO summit in The Hague, where members agreed to increase defense spending to 5% of GDP, has further heightened the stakes.

The illicit acquisition of technology and intelligence will help North Korea understand and potentially counter the growing military strength of the EU and NATO.Furthermore, the increase in partnerships between European and South Korean defense firms – such as Poland’s recent $6.5 million deal for K2 Black Panther tanks – presents new opportunities for North Korean hackers to exploit vulnerabilities and steal valuable intellectual property.

The Russia-North Korea cybercrime Nexus

Perhaps most concerning is the growing collaboration between North Korean hackers and Russian ransomware groups. A 2024 report by Palo Alto Networks’ Unit42 revealed that North Korean cyber actors were working with the Play ransomware gang. This partnership allows North Korea to gain access to new targets and generate additional revenue while simultaneously disrupting critical infrastructure in Europe.

Pro Tip: Organizations should implement robust multi-factor authentication, regularly update software, and provide cybersecurity awareness training to employees to mitigate the risk of falling victim to phishing or ransomware attacks.

Threat Actor	Primary Motivation	Target Sectors	Key Tactics
North Korea	Financial Gain, intelligence Gathering	Finance, Technology, Defense, Government	Cryptocurrency Theft, Cyber Espionage, Ransomware (via partnerships)
Russia	Geopolitical Influence, Disruption	Government, Energy, Media	Disinformation Campaigns, Cyber Attacks, Espionage
China	Economic Espionage, Technology Transfer	Technology, Manufacturing, Intellectual Property	Supply Chain Attacks, Intellectual Property Theft

Implications for Ukraine and Regional Security

The ENISA report suggests that North Korean cyber activity could have far-reaching consequences, potentially impacting the ongoing conflict in Ukraine. By gaining access to European defense firms that support Ukraine, North Korean hackers could steal critical facts about supply routes and weapon shipments, passing it onto Russian forces.This could substantially hinder Ukraine’s ability to defend itself.

The increasing sophistication and expanding reach of North Korean cyber operations demand a holistic and coordinated response from the EU and NATO. Treating North Korea solely as a regional pariah is no longer sufficient. A proactive cybersecurity strategy,focused on threat intelligence sharing,enhanced defenses,and international cooperation,is essential to mitigating this growing threat.

What steps should the EU take to improve its cybersecurity posture against North Korean threats? How can international collaboration be strengthened to disrupt North Korea’s illicit cyber activities?

Looking Ahead: The Evolving Cyber Threat Landscape

The cybersecurity landscape is constantly evolving, with new threats emerging at an unprecedented rate. Organizations and individuals must remain vigilant and proactive in protecting themselves against cyberattacks. Staying informed about the latest threats, implementing robust security measures, and fostering a culture of cybersecurity awareness are crucial for mitigating risk and safeguarding digital assets. The convergence of geopolitical tensions and sophisticated cyber capabilities presents a complex challenge that requires ongoing attention and investment.
