Universal Health Services (UHS), a Fortune 500 hospital and healthcare services provider, has reportedly shut down systems at healthcare facilities around the US after a cyber-attack that hit its network during early Sunday morning.
UHS operates over 400 healthcare facilities in the US and the UK, has more than 90,000 employees and provides healthcare services to approximately 3.5 million patients each year.
The Fortune 500 corporation had annual revenues of $11.4 billion in 2019 and it is 330th on Forbes' ranking of US largest public companies.
According to reports coming from UHS' employees, UHS hospitals in the US including those from California, Florida, Texas, Arizona, and Washington D.C. are left without access to computer and phone systems.
At the moment the affected hospitals are redirecting ambulances and relocating patients in need of surgery to other nearby hospitals.
"When the attack happened multiple antivirus programs were disabled by the attack and hard drives just lit up with activity," one of the reports reads.
"After 1min or so of this the computers logged out and shutdown. When you try to power back on the computers they automatically just shutdown."
"We have no access to anything computer based including old labs, ekg's, or radiology studies. We have no access to our PACS radiology system."
Employees were also told to shut down all systems to block the attackers' from reaching all devices on the network.
