EU Agency Warns of Surge in Cyber Threats Against Public Infrastructure

A new report from the European Union Agency for Cybersecurity (ENISA) reveals a surge in cyber threats against EU public administrations and critical infrastructure. Ransomware attacks, in particular, have caused significant disruptions, including recent incidents at major European airports like Berlin Brandenburg (BER) and London Heathrow.

Between July 2024 and June 2025, public administration emerged as the most targeted sector, accounting for 38.2% of incidents. The transport sector followed closely with 7.5%. Ransomware was identified as the threat with the most impact, with recent attacks causing computer disruptions at airports.

The report also highlights the increasing sophistication of cyberattacks. Over 80% of globally observed social engineering activities are now AI-assisted, including the creation of fake instructions. While DDoS attacks make up 77% of reported incidents, their damages, though significant, are not as high as those from ransomware. 'Hacktivists' are the main perpetrators behind these attacks.

ENISA's report underscores the intensifying threat to Europe's digital infrastructure. Diplomatic and state institutions are particularly targeted for cyber espionage campaigns. As ransomware continues to pose the greatest impact, it is crucial for EU member states to strengthen their cybersecurity measures and collaborate effectively to combat these evolving threats.
