Cybersecurity Threat Intelligence Briefing — December 11, 2024
ENISA's Threat Landscape 2024 report details ransomware dominance, hacktivist campaigns, and supply chain weak points European defenders must fold into 2025 planning.
Executive briefing: The European Union Agency for Cybersecurity (ENISA) released the Threat Landscape 2024, confirming ransomware as the most disruptive threat, documenting sustained pro-Russian hacktivist DDoS operations, and mapping how third-party compromises across managed service providers and software distributors amplified impact. Zeph Tech is updating European risk registers and tabletop scenarios so CISOs can show alignment with ENISA's priority control set.
Key threat observations
- Ransomware gravity. ENISA measured ransomware as the top incident class for the seventh consecutive year, noting data theft and destructive wipers accompanying extortion campaigns against healthcare and manufacturing.
- Hacktivism surge. Politically motivated DDoS and defacement campaigns tied to the Russia-Ukraine conflict and Middle East tensions persisted, frequently hitting EU transportation and government services.
- Supply chain exposure. Compromise of IT service providers and software updates remained high-impact entry points, echoing 2024 incidents involving remote monitoring and payroll platforms.
Control alignment
- NIS2 Articles 21 and 23. Validate incident response and reporting procedures against ENISA's case studies, ensuring 24-hour notification workflows reflect multi-party breaches.
- ISO/IEC 27001:2022 A.5.20. Strengthen supplier due diligence and continuous monitoring for managed service providers called out by ENISA.
Detection and response priorities
- Harden DDoS mitigation runbooks across public-sector portals and transportation systems, incorporating threat intel indicators ENISA enumerated.
- Expand ransomware containment exercises to include destructive tooling and data leak site monitoring with legal and crisis communications stakeholders.
Enablement moves
- Share ENISA findings with European boards, highlighting sector-specific ransomware playbooks and planned investments in backup immutability and identity security.
- Map ENISA's supply chain recommendations to vendor risk scoring models and audit questionnaires heading into 2025 renewals.
