A ransomware attack appears to have taken down all IT systems at Universal Health Services (UHS), which operates 400 hospitals and behavioral health facilities in the US and the UK.
UHS employees began reporting problems on Monday via Reddit; the attack has been shutting down computers at various hospitals, forcing them to turn away patients, they say.
One UHS employee based in Arizona told PCMag that the disruption has been blamed on ransomware infecting hospital systems. “Everything is down. No access to any computer at all,” the employee said. The hospital has only recently managed to restore the phone system.
