Irish Prime Minister Micheal Martin said the attack was a “heinous” one that targeted patients and “the Irish public.” Health Service Executive chief clinical officer Colm Henry said the attack had “a profound impact on our ability to deliver care” and has also shut down the system used to pay health care workers.
He told Irish broadcaster RTE that the disruptions would only “mount in the coming days and weeks.”
Ransomware attacks are typically carried out by criminal hackers who scramble data, paralyzing victims’ networks, and demand a large payment to decrypt it. Irish officials say a ransom has been demanded but they will not pay it.
Conti, a Russian-speaking ransomware group, was demanding USD 20 million, according to the ransom negotiation page on its darknet site viewed by The Associated Press. The gang threatened Monday to “start publishing and selling your private information very soon” if the money was not paid.
“The government will not be paying any money,” Justice Minister Heather Humphreys told broadcaster RTE. “We will not be blackmailed.”
The Irish Association for Emergency Medicine urged people not to turn up at hospitals’ emergency departments unless they have a genuinely urgent need to do so. It said that electronic ordering of blood tests, X-rays and scans is not available, and clinicians have no access to previous X-rays or scan results. Many hospitals’ telephone systems are also not functioning because they are carried on computer networks, it added.
The Health Service Executive said in a statement late Monday that there were “serious concerns about the implications for patient care arising from the very limited access to diagnostics, lab services and historical patient records.”
The health service said it was working methodically to assess and restore approximately 2,000 IT patient-facing systems, each supported by infrastructure, multiple servers and devices.
“Our priority is keeping our patients safe and maintaining essential care and support services,” it said.
Ransomware attacks are an increasing problem for private companies and public bodies around the world.
The Thai affiliate of Paris-based insurance company AXA and a public health provider in New Zealand were both dealing with ransomware attacks on Tuesday.
In the U.S., the nation’s largest fuel pipeline was hit with a ransomware attack earlier this month. The disruption of the Colonial Pipeline caused long lines at gas stations due to distribution problems and panic-buying, draining supplies at thousands of gas stations.
