The incident was described as a 'major network incident' that knocked offline key infrastructure services. The attack impacted both postal services and banking operations, suggesting a significant cybersecurity breach affecting critical national infrastructure. The disruption affected millions of French citizens who rely on these digital services for daily financial and postal transactions.

Technical details

La Poste suffered a major network incident that knocked offline all information systems including main website, mobile app, digital identity service, and Digiposte document storage platform.
