Over the past few days there has been an unprecedented worldwide cyber-attack that effected several countries and organisations. Security researchers are warning to expect more of these attacks (including variations) to happen in the coming days.
The threat posed by such cyber-attacks can be minimized by following basic steps:
- Do not click on email links or attachments that come from individuals you do not know. Also, extra care must be placed to check that the email sender address is correct. Ask yourself – was I expecting this email? Is this email too good to be true? Is the email using a tone which does not usually come from the sender? If in doubt, don’t click!
- Check that Windows Update is enabled and when prompted to install patches/reboot the machine, you do so without delays. Speak to your trusted ICT provider and/or from where you bought your machine if in doubt.
- Check that your home computer/laptop has antivirus software installed. Also, check that the latest antivirus definition file is being downloaded on your machine. Speak to your trusted ICT provider and/or from where you bought your machine if in doubt.
- Take backups (copies) of your most important data stored on your computer/laptop at home. If you use an external hard disk for the backup, do not leave the external hard disk connected to the computer/laptop when you are not doing a backup.
- Is your home computer/laptop slowing down unexpectedly? Are you seeing files changing without you knowing? These are potential signs of your machine having a virus. Speak to your trusted ICT provider immediately if the case.
