Grands évènements sportifs - Évaluation de la menace 2023

ANSSI evaluates the heightened cyber threat landscape around France-hosted major sporting events (Rugby World Cup 2023 and Paris 2024), warning of high-probability, high-impact attacks including ransomware, DDoS extortion, destructive wipers, hack-and-leak operations, supply‑chain compromises and targeted espionage against delegations and infrastructure; the report describes historical incidents, assesses threat likelihoods, and issues practical defensive recommendations (hardening, segmentation, backup strategy, logging/EDR and incident exercises).
