Marista Group

The organisation operates under several aliases, including Marista Group Hospitals, Grupo Marista, Marista Group Health Facilities, and Marista Group. Its headquarters is situated in Italy. The group runs hospitals and health facilities that deliver medical care to patients across the regions where it is present. In addition to its healthcare operations, the network incorporates a university that is affiliated with the medical institutions.

A notable distinguishing attribute of the Marista Group is its capacity to maintain essential clinical services during information technology disruptions by resorting to manual procedures. This capability was demonstrated during a cyberattack on March 13, 2022, which targeted the group’s operational systems across affiliated hospitals and a university. The attack affected specific facilities such as Hospital Cajuru and Marcelino Champagnat, forcing their IT systems offline for multiple days. While the networks were unavailable, staff continued to provide patient care and managed medical records and medication administration through manual processes. Public‑facing websites for the affected institutions displayed maintenance notifications throughout the outage. The incident illustrates the group’s operational resilience and its preparedness to sustain critical healthcare functions under adverse conditions.
