The recent global cyber-attack used ransomware to target computers running older and out-of-date operating systems. The majority of these computer were still using Windows XP, however some were using Windows 7. So far, we are not aware of any cases that affected Windows 10 computers.
As well as a reminder to keep operating systems up-to-date, this cyber-attack reinforces the need to backup your data.
Most Ransomware works by encrypting your data and in some cases the data is completely unrecoverable whether you pay the ransom or not. We strongly recommend that you do not pay the ransom in the event you fall victim to ransomware as there is no guarantee you will get your data back and you’ll be more likely to be targeted in future attacks.
Making sure that you have a strong backup plan in place to maintain the safety and security of your data will mean that even if you do get ransomware you will be able to recover your data.
We recommend a 3-2-1 backup strategy which involves maintaining backups in 3 locations, on at least 2 different types of media, with one backup being offsite.
An example of this strategy would be:
- Backup #1: External Hard Drive
- Backup #2: Removable Storage – e.g. SD Cards, USB Flash Drives
- Backup #3: Cloud based Backup – e.g. DropBox, OneDrive
