France confronts rising cyber and hybrid warfare threats in 2026

In 2026, cyber warfare has become a daily reality for states and firms, with attacks blurring the line between state‑sponsored operations and organized crime. France now ranks among the three most targeted nations worldwide, behind the United States and the United Kingdom, according to the French National Cybersecurity Agency (ANSSI).

The volume of distributed‑denial‑of‑service (DDoS) attacks surged 358 % in 2025, peaking at 7.3 terabits per second within 45 seconds, and such services are now sold on dark‑web markets for as little as $15 a month. Artificial‑intelligence tools have become the primary offensive weapon, automating hyper‑personalised phishing campaigns and driving a 700 % global rise in deep‑fake content between Q1 2024 and Q1 2025. Critical infrastructure, public administrations and the financial sector are frequent targets.

French authorities describe this environment as a hybrid war that intertwines state actors, criminal networks and technology. Recent incidents illustrate the impact on everyday life: a cyber‑attack on a health‑software platform compromised data of 15 million French citizens, and the cryptocurrency platform Waltio suffered a large‑scale data breach. The Gendarmerie nationale reports weekly kidnappings linked to cyber‑criminal activities. Supply‑chain intrusions, pre‑positioned implants and ransomware are now considered matters of national security.
