An apparent ransomeware attack on Universal Health Services created a mass computer outage in facilities across the country, rendering some equipment useless and forcing facilities to resort to paper backup charting. UHC is a Fortune 500 company operating over 250 medical facilities and employing over 90,000 people across the entire US. The attack caused what employees described as “a scramble” and resulted in up to 6-hour waiting times in some ERs, though the company has reported that it appears no patient or employee data was accessed or copied.
