A ransomware attack on a national hospital chain nearly brought Las Vegas hospitals to their knees. Another attack in Oregon abruptly shut down alerts tied to patient monitors tracking vital signs. In New York, one county’s only trauma center briefly closed to ambulances, with the nearest alternative 90 miles away.
Multiple attacks were carried out in recent months against U.S. hospitals, suspending some surgeries, delaying medical care and costing hospitals millions of dollars.
