Major Cyberattack Disrupts La Poste and French Banking Services Ahead of Christmas On Monday, December 22, 2025, a large-scale DDoS (Distributed Denial of Service) cyberattack crippled critical services of La Poste, France’s national postal operator, and its banking subsidiary, La Banque Postale. The attack, which began around 6:30 AM, rendered key platforms—including Colissimo (parcel shipping), Digiposte (digital storage), and postal labeling systems—unavailable, disrupting last-minute holiday deliveries and financial services just 48 hours before Christmas. The outage was severe enough to prompt La Poste’s management to authorize the closure of select post offices, though payment systems remained operational due to a separate, unaffected data stream. While the group confirmed the incident as a DDoS attack, some experts questioned whether the disruption stemmed from a more sophisticated breach, given the scale of the downtime. Other major French banks—including Caisse d’Épargne and Banque Populaire—also experienced slowdowns or service interruptions the same morning. Both institutions attributed the issues to "dysfunction" rather than a cyberattack, though speculation persists about a potential coordinated campaign. The attack’s timing exacerbated its impact, as millions of customers relied on La Poste’s services for urgent parcel shipments and digital banking access. While La Banque Postale’s mobile app and website gradually resumed functionality, La Poste’s main site remained offline for hours. The incident follows a similar disruption on December 20, raising concerns about repeated targeting of critical infrastructure. No group has claimed responsibility, but the scale and persistence of the attacks suggest possible state-backed involvement, with some analysts pointing to pro-Russian hacking collectives active in recent French cyber incidents. As of reporting, no data breaches or unauthorized system access have been confirmed.
