Marista Group

Profile narrative

Marista Group Hospitals, also known as Grupo Marista or Marista Group, has its headquarters in Italy. The organization oversees a collection of affiliated hospitals and an associated university. It delivers healthcare services through its hospital facilities and supports educational activities via its university. The group's operations span both medical and academic domains.

On March 13, 2022, the Marista Group experienced a cyberattack that disrupted operational systems across its affiliated hospitals and the associated university. The attack affected Hospital Cajuru and Marcelino Champagnat, among other facilities. IT systems were taken offline for several days, requiring staff to handle medical records and medication administration manually. Patient care continued without interruption despite the network outage.

During the incident, employees worked without access to the network, relying on paper-based processes to maintain safety and continuity of care. Public-facing websites displayed maintenance notifications to inform visitors of the temporary disruption. The episode demonstrated the organization's capacity to sustain clinical operations while technical systems were unavailable. No information indicated that patient outcomes were adversely affected during the outage.

The Marista Group includes both hospital management and an academic affiliation. Its headquarters is located in Italy, and the referenced hospitals are part of its network. The 2022 ransomware incident remains a documented example of cyber resilience within the organization's history.
