San Gorgonio Memorial Hospital cyberattack disrupts patient-care operations

San Gorgonio Memorial Hospital in California identified suspicious activity on its computer network on November 10, 2022, following unauthorized access that had begun in late October. The hospital activated incident-response procedures, isolated selected systems and investigated the intrusion with external forensic specialists. A hospital spokesperson confirmed that the incident disrupted IT operations and that patient-care operations returned to normal on November 16. The incident consequently caused a temporary interruption or degradation of supporting hospital processes affecting healthcare delivery. Subsequent disclosures also established unauthorized access to patient-related documents, but the exact clinical functions impaired and the duration of each interruption were not publicly specified.
