Yuma Regional Medical Center

Yuma Regional Medical Center (YRMC) operates as a healthcare provider delivering essential medical services. Based in the United States of America, its core function involves patient care within its designated regional scope. The organization maintains critical information systems necessary for its clinical and administrative operations, handling sensitive patient data including names, Social Security numbers, health insurance details, and medical information as part of its service delivery. This data management is fundamental to its role in the healthcare sector.

YRMC experienced a significant cybersecurity incident in April 2022. Unauthorized actors accessed its network over several days, culminating in a detected ransomware attack on April 21st. The attack compromised sensitive personal and health information belonging to over 700,000 individuals. Upon detecting the intrusion, YRMC promptly shut down affected systems to contain the breach. The organization engaged external cybersecurity experts and notified law enforcement agencies, including the FBI. Initial assessments indicated no confirmed data compromise, but subsequent investigations conclusively determined that attackers had exfiltrated files containing the sensitive patient data. Although no ransomware group publicly claimed responsibility for the attack, YRMC implemented remediation efforts which required keeping critical systems offline temporarily. Patient care continued during this period utilizing established backup procedures. In response to the confirmed data breach, YRMC offered affected individuals credit monitoring and identity theft protection services.
