DIGITAL SHADOWS: Response to Major “WannaCry” Ransomware attack

“We have seen ransomware attacks against the NHS in the past including Barts Health Trust in January. However this looks to be more serious and is potentially targeting core systems used by multiple hospitals. Unfortunately the ransomware ‘business model’ is very profitable for cyber criminals and we’ve seen multiple reports of organisations paying out in the past,” said Rick Holland, Vice President, Strategy, Digital Shadows. “Keeping up-to-date with ransomware is not easy, there are many variants.
