Europe's Energy Infrastructure Under Siege: Cyber Attacks Surge 67% in H1 2025

Europe's energy infrastructure is under siege. Since 2025, hostile foreign actors have stepped up attacks on energy grids, with nearly half involving unauthorised access to operational technology systems. The EU has sounded the alarm, elevating the risk to a top-tier priority.

In the first half of 2025 alone, the European Union Agency for Cybersecurity (ENISA) reported a staggering 67% increase in cyber incidents targeting energy-related entities. Experts warn that Europe's interconnected grids are vulnerable to 'cascade effects', which could trigger regional blackouts.

The EU fears these attacks are part of a broader strategy to undermine European resilience. Russia, China, and Iran are identified as the leading suspects, with security experts ranking hybrid digital warfare among the gravest threats to EU stability in 2025. These nations are deemed the most capable state actors in this domain.

The European Commission is racing to bolster defences, accelerating plans for a bloc-wide 'Cyber Shield' mechanism. However, with attacks increasing in tempo and sophistication, Europe's energy infrastructure faces an unprecedented challenge.
