Is there a best practice way to mitigate time-bomb ransomware attack attempts – especially if auto-backups are used?

The most important thing is to be careful about how you restore any data. Check and clean the data you are about to restore – knowing that there’s a possible threat in there.

You can report ransomware and other cyber attacks to Action Fraud – the National Fraud and Cyber Crime Reporting Centre.  Tel 0300 123 2040
