Healthcare giant UHS hit by ransomware attack, sources say

Universal Health Services, one of the largest healthcare providers in the U.S., has been hit by a ransomware attack.
The attack hit UHS systems early on Sunday morning, according to two people with direct knowledge of the incident, locking computers and phone systems at several UHS facilities across the country, including in California and Florida.
One of the people said the computer screens changed with text that referenced the “shadow universe,” consistent with the Ryuk ransomware.
