Hospital chain attack part of ongoing cybersecurity concerns
CHICAGO — Diverted ambulances. Despite the lingering questions, the incident underscores the growing concerns surrounding ransomware attacks on health care systems with patient care at stake. Brett Callow, a threat analyst with cybersecurity provider Emsisoft, said the incident could be “the most significant attack on the health care sector to date” if all CommonSpirit hospitals and other facilities were affected. Callow said one of the largest known attacks within health care came in September 2020 when a ransomware attack struck all 250 health care facilities owned by Universal Health Services. “Beyond that, these incidents can have a long-term impact on patient outcomes — delaying treatments, for example.” In 2020, the FBI and other federal agencies warned that they had credible information that cybercriminals could unleash a wave of data-scrambling extortion attempts against U.S. hospitals and health care providers.
