Ransomware hit on Irish public health system shuts down all IT systems

The Health Service Executive (HSE), Ireland's national healthcare provider, has been the victim of a sophisticated cyber attack that started as a fairly routine Distributed Denial of Service attack yesterday, before successfully penetrating systems early this morning four years to the day after the NHS was affected by the WannaCry virus.

"There is a significant ransomware attack on the HSE IT systems. We have taken the precaution of shutting down all our our IT systems in order to protect them from this attack and to allow us fully assess the situation with our own security partners," said HSE in a statement.

"We are working with all of our major IT security providers and the national security cyber team are involved and being alerted," he revealed.

Hospital groups in the country are announcing that they are "largely operating on back-up manual systems" and urging patients to not visit hospital unless in an emergency.

There have been cancellations and disruption to services at a number of hospitals, and the booking system for Covid jabs is not working. The disruption is likely to continue over the weekend.

In 2017, it took four days for the NHS to recover from the impact of WannaCry after more than a third of NHS trusts across the UK suffered disruption, and over 20,000 appointments were cancelled.
