Healthcare giant UHS hit by ransomware attack, sources say
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.
The Ryuk ransomware is linked to a Russian cybercrime group, known as Wizard Spider, according to security firm Crowdstrike.
Ryuks operators are known to go big game hunting and have previously targeted large organizations, including shipping giant Pitney Bowes and the U.S.
Some ransomware operators said earlier this year that they would not attack health organizations and hospitals during the COVID-19 pandemic, but Ryuks operators did not.
Last week, police in Germany launched a homicide investigation after the death of a woman, who was diverted to another hospital following a ransomware attack.
