Universal Health Services, one of the largest hospital and healthcare services providers in the US, confirmed today that the IT network that supports its facilities is offline in the wake of what it called “an IT security issue.”
“We implement extensive IT security protocols and are working diligently with our IT security partners to restore IT operations as quickly as possible. In the meantime, our facilities are using their established back-up processes including offline documentation methods. Patient care continues to be delivered safely and effectively,” a UHS spokesperson said in a statement provided to Dark Reading. “No patient or employee data appears to have been accessed, copied or misused.”
The company’s email system appeared to still be down today, as the spokesperson responded to inquiries about the attack via a personal account after an attempt was made to reach the company via its corporate email system.
TechCrunch reported today that the event was a ransomware attack, and that it had locked out UHS users from computer and telecommunications systems at healthcare and hospital facilities nationwide. One source told TechCrunch that computer screens were replaced with text that included a mention of “shadow universe,” the typical calling card of Ryuk ransomware’s ransom note.
UHS has hundreds of facilities in the US and UK and reported revenue of $11.4 billion in 2019.
