Ascension Health Ransomware Attack Disrupts Care Across Multiple States
In May 2024, Ascension — one of the largest U.S. healthcare systems — suffered a crippling ransomware attack that made electronic health records inaccessible across multiple states. Healthcare workers reverted to manual documentation. Emergency services were diverted. The MyChart system went dark. The incident exposed a fundamental gap: even the largest healthcare operators can be brought down when a single system fails under attack. For the thousands of mid-market regional hospitals with a fraction of Ascension's resources, the vulnerability is not smaller. It is greater.
