Kettering Health, a major Ohio-based healthcare network with multiple medical and emergency centers, suffered a severe ransomware attack leading to a system-wide technology outage lasting over two weeks. The attack disrupted electronic health records (Epic system), forcing staff to revert to manual (pen-and-paper) operations. Critical services were severely impacted: emergency rooms closed, medication refills delayed (risking patient seizures), ambulances diverted due to prolonged wait times, and life-saving procedures canceled—including MRIs, cancer follow-ups, open-heart surgery prep, and chemotherapy. Phone lines and digital communications failed, leaving patients unable to contact doctors. While Kettering restored *core* EHR functions, the Interlock ransomware gang claimed responsibility, stating they had compromised and secured vital files. The attack mirrors a broader 2024 trend of devastating healthcare breaches, though Kettering has not confirmed data exfiltration or the scope of stolen records. The operational chaos threatened patient safety, with some facing potentially fatal delays in critical treatments.
