Summary

Hide ▲

Distributed denial of service (DDoS) attacks, primarily driven by hacktivist groups, represented the majority of cybersecurity incidents in the public sector in 2024. Although DDoS attacks were the most frequent, data breaches and ransomware incidents caused significant disruption. The public sector, which manages large volumes of sensitive data and delivers critical services, remains a key target for cyber threats. The European Union Agency for Cybersecurity (ENISA) reported that 60% of cybersecurity incidents in the public sector were DDoS attacks, with 63% attributed to hacktivist groups. Cybercriminals and state actors were responsible for most of the remaining incidents, which included data breaches and ransomware attacks. The public sector's resilience to cyber threats is still not optimal, and ENISA warns of increased attacks in the mid- to long-term.

    ENISA Report: Hacktivist-Driven DDoS Attacks Dominate Public Sector Cyber Incidents in 2024

    In 2024, DDoS attacks, primarily driven by hacktivist groups, represented the majority of cybersecurity incidents in the public sector. Data breaches and ransomware attacks, though less frequent, caused significant disruption. The public sector's management of sensitive data and delivery of critical services make it a key target. ENISA warns of increased attacks in the mid- to long-term, particularly hacktivist DDoS, state-backed cyber-espionage, and opportunistic ransomware and data breaches.
