RMcKinley Christian Health Care Services (RMCHCS) in Gallup, NM submitted a report regarding a ransomware attack in February 2021 that resulted in patient data exfiltration.

The attack in February conducted by the Conti ransomware gang had involved the theft of a variety of sensitive data, consisting of job application information, background check records, employee reports, and protected health information (PHI) of patients.

An evaluation of the data files likely accessed by the threat actors was completed on April 30, 2021, after which, RMCHCS sent notification letters to the impacted individuals.

RMCHCS explained that the attackers may have accessed these data: names, birth dates, telephone numbers, email addresses, addresses, dates of service, driver’s license numbers, password numbers, tribal ID numbers, Social Security numbers, health insurance details, medical record numbers, names of healthcare providers, diagnoses, treatment information, prescribed medicine details, financial account information, and billing and claims details.
