Windows ransomware has become a major problem for small and medium-sized businesses (SMBs), a survey by Datto, a company that provides IT solutions for managed service providers (MSPs), shows, with 91% of MSPs in Australia and New Zealand reporting attacks on SMBs in the last two years.

Nine days ago, the Victorian Government announced that it would be providing $200,000 for a program to help Microsoft train more people in the use of its software. It came, ironically, just a day after regional Victorian hospitals were hit by ransomware – something that, by far, only attacks Microsoft's Windows operating system.

Victorian regional health service Barwon Health is one among numerous entities in the state's health network to be hit by a ransomware attack. Details are expected to be announced later today by the state's Premier, Daniel Andrews.
