France’s La Poste Groupe experienced a widespread online service outage beginning on December 22, 2025, disrupting access to key postal, banking, and digital identity platforms. The organization attributed the incident to a denial-of-service (DoS) attack and emphasized that no customer data had been compromised.
According to La Poste’s public statements, the disruption rendered several of its internet-facing services inaccessible between December 22 and 24. Impacted systems included the main postal website laposte.fr, parcel tracking via Colissimo, the Digiposte secure document vault, and online banking through La Banque Postale. Several digital identity and authentication services—including La Poste’s Identité Numérique—were also referenced in independent reporting as being affected.
During the outage, La Poste said some call centers were less accessible, though normal service was later restored. While online and mobile platforms were unavailable at times, core financial services such as card payments, ATM withdrawals, and SMS-based authentication for online transactions reportedly remained operational.
La Poste described the event as a denial-of-service incident rather than a data breach and said national cybersecurity authorities were informed. The Associated Press reported that a pro-Russian group known as Noname057 claimed responsibility, while other outlets including The Guardian noted that attribution remained unconfirmed. Euronews referenced earlier service instability and recalled a similar DDoS claim in 2024 by Turk Hack Team.
Tech industry outlets attributed the disruption to a distributed denial-of-service (DDoS) attack, citing traffic anomalies observed during the incident window. Cloudflare Radar and other monitoring tools registered significant network spikes consistent with DDoS patterns.
The outage underscores the intertwined nature of digital identity and critical infrastructure services in France. La Poste’s Identité Numérique platform supports authentication and trusted digital interactions across government and financial services, while the organization’s broader digital transformation has seen continued expansion of eID and secure document services. France’s ongoing rollout of digital driver’s licenses and forthcoming mobile identity cards highlights the increasing importance of robust, resilient digital authentication frameworks.
