Mutuelle Nationale des Hospitaliers et des professionnels de la santé et du social

Mutuelle Nationale des Hospitaliers et des professionnels de la santé et du social, commonly known as MNH, is a French mutual organization headquartered in France. The entity serves professionals working within the healthcare and social sectors, operating as a mutual to provide services to its member base. Its operational footprint is national, focused on the French market, and it maintains digital infrastructure including member portals and telephone platforms to manage member interactions and process requests. The organization's core function involves supporting its constituents through these service channels, though specific product details or quantitative measures of its size are not provided in the available information. Its positioning within the French social protection landscape is that of a specialized mutual for a defined professional constituency.

In February 2021, MNH was the target of a significant cyberattack attributed to the RansomExx threat actor. This incident prompted the organization to proactively disconnect its systems in an effort to contain the breach. The attack resulted in widespread and extended service disruptions, rendering the organization's websites, member portals, and telephone platforms completely unavailable. Consequently, MNH experienced substantial delays in processing member and customer requests for a prolonged period. While external security analyses suggested the attack may have exploited the critical Citrix/Netscaler vulnerability CVE-2019-19781, the mutual did not officially confirm the specific initial vector of compromise. Management publicly acknowledged the severe operational impacts and committed to a policy of transparent communication throughout the recovery and restoration process for the affected services.
