Ransomware virus scams

Please may I request answers to the following questions:

1. Whether the council has fallen victim to a ransomware virus scam (a definition of which can be found at: http://www.trendmicro.com/vinfo/us/security/definition/ransomware), or has been made aware that it has transmitted a ransomware virus scan from its email server, between 1 January 2014 and 31 July 2016 inclusive, in whichever format is easiest to supply; and

2. If the answer to question 1) is "yes", how many times the council has fallen victim;

3. If the answer to question 1) is "yes", how many machines (PCs or laptops) were affected, and what happened to them; and

4.  If the answer to question 1) is “yes”, whether the council paid the ransom, and if so, how much it paid in pounds sterling, in whichever format is easiest to supply.
