The Coombe Women and Infants University Hospital in Dublin has confirmed it was the victim of a cyberattack overnight.
Services at the hospital are continuing as normal on Thursday, a statement said, with an investigation into the attack under way.
There is currently no evidence of impact beyond the Dublin hospital, the Health Service Executive (HSE) said.
“We wish to reassure all of those accessing our services that these services are continuing as normal,” the Coombe Hospital said in a statement.
“We have locked down all our IT systems on a precautionary basis and are working closely with the HSE to resolve this matter.”
The HSE also confirmed the ransomware attack on the hospital’s IT systems on Thursday, and said work was under way to assess if there “is any broader impact”.
“We are aware of a ransomware attack on IT systems at the Coombe. This has impacted several systems in the hospital,” a HSE statement said.
“HSE teams are working with colleagues in the Coombe and have disconnected the facility from the National Health Network.
“At this point we have not seen evidence of an impact external to the Coombe Hospital but we are continuing, with external support, to assess whether there is any broader impact. We will share further information as we have it.”
It follows a major cyberattack on the HSE earlier this year, which caused the shut-down of many systems and nationwide disruption across the health service.
