PARIS, December 23, 2025 – France’s national postal service, La Poste, was brought to a standstill Monday by a suspected distributed denial-of-service (DDoS) attack, disrupting services across the country. The company described the incident as “a major network incident” impacting “all of our information systems.”
Postal Service Disrupted as Cyberattacks Escalate in France
A widespread cyberattack knocked out key services at La Poste, adding to a recent surge in cybersecurity incidents targeting French institutions.
- La Poste’s online services, including mail and banking, are temporarily unavailable.
- The banking arm, La Banque Postale, also reported disruptions to its mobile app and online banking.
- A Russian hacktivist group has claimed responsibility, though attribution remains unconfirmed.
- The attack follows a series of cybersecurity breaches affecting the French government.
The outage affects La Poste’s website, mobile app, and online mail and banking services, though customers can still complete transactions in person, according to a translated statement. La Banque Postale, the postal service’s banking branch, also announced that the cyberattack was “temporarily making our customers’ access to their mobile app and online banking space unavailable,” according to a post on X.
What is a DDoS attack? A distributed denial-of-service attack overwhelms a system with traffic from multiple sources, rendering it inaccessible to legitimate users.
While a Russian hacktivist group has reportedly claimed responsibility for the attack, according to reports, authorities have not yet confirmed the source. This incident occurs amid a broader pattern of cyberattacks targeting French entities.
Recent Cybersecurity Incidents in France
The French government has been grappling with a series of cybersecurity challenges in recent weeks. Authorities are investigating the discovery of remote control software found on a passenger ferry, raising concerns about potential foreign interference.
Last week, the French Interior Ministry disclosed a data breach involving compromised email accounts and the theft of sensitive documents, including criminal records. A 22-year-old suspect, whose identity has not been released, was subsequently arrested in connection with the breach.
At this time, it remains unclear whether these incidents are connected. The escalating frequency of these attacks underscores the growing threat landscape facing France and the need for robust cybersecurity measures.
