Communauté de communes Cœur de Maurienne Arvan

It is a French intercommunal structure (communauté de communes) that groups several municipalities in the Cœur de Maurienne Arvan area. It provides shared administrative and IT services to its member communes, supporting functions such as social services, tourism offices, and town hall operations. The organisation enables collective management of public services across the territory, allowing municipalities to pool resources and expertise. Its scope includes coordinating services that benefit residents and local businesses within the Maurienne valley. By offering a common IT infrastructure, it facilitates the delivery of digital services to the public sector entities it serves.

While explicit size figures are not provided, the 2022 incident affected multiple local entities across the region, indicating a broad reach. The organisation serves a network of municipalities and associated public offices, as evidenced by the disruption of services across social services, tourism offices, and town halls during the cyber attack. The shared nature of its infrastructure means that an incident can impact numerous local administrations simultaneously. This demonstrates its role as a central service provider for the intercommunal territory. The organisation's headquarters is located in France, though the specific city is not disclosed in the source material.

The organisation is distinguished by its responsibility for maintaining a shared IT platform that underpins essential municipal services. Its notable competency includes implementing preexisting safeguards that preserved critical data during the crypto‑virus attack of January 2022. The incident also highlighted its capacity to establish emergency contact channels for vital services such as childcare, urban planning, and utilities while recovery efforts were underway. As a public intercommunal entity, it is owned by its member communes and operates under French local government law, with no private parent or subsidiary structure indicated in the available information. Law enforcement opened an investigation following the attack, underscoring the organisation's accountability to regional authorities.
