Security News > 2020 > October > UHS restores hospital systems after Ryuk ransomware attack
Universal Health Services, a Fortune 500 hospital and healthcare services provider, says that it has managed to restore systems after a September Ryuk ransomware attack.
The ransomware attack the healthcare provide refers to as a "Security incident" took place during the early hours of Sunday, September 27, and it forced UHS employees to shut down all systems to block the malware from spreading to unaffected network systems.
UHS has since restored most affected computing systems at behavioral and acute care health hospitals, also bringing back systems vital to hospital operations including those needed for laboratory and for managing patient electronic records.
UHS hasn't disclosed the nature of the nationwide September attack on its systems in the initial disclosure statement or today's report and 8K filing.
Based on info shared by Advanced Intel's Vitali Kremez, the attack on UHS' systems most likely started via a phishing attack.
