In early March, the Champaign-Urbana Public Health District got hit and had to pay $350k to the blackmailers to regain access. As advised by Interpol and so many others, these are the minimums for security here;
Only open emails or download software/applications from trusted sources;
Do not click on links or open attachments in emails which you were not expecting to receive, or come from an unknown sender;
Secure email systems to protect from spam which could be infected;
Backup all important files frequently, and store them independently from your system (e.g. in the cloud, on an external drive);
Ensure you have the latest anti-virus software installed on all systems and mobile devices, and that it is constantly running;
Use strong, unique passwords for all systems, and update them regularly.
