Last night, the HSE became aware that they were the victim of a serious and sophisticated ransomware attack. At the time of writing, there is very little detail on the exact nature of the attack, but the following information has been made public.
The attack was coordinated by humans and not automated by a botnet.
The attack targeted the HSE servers that host their patient record database.
No ransom request has been made at the time of reporting and all other hospital systems remain unaffected.
