We have all heard in the news the latest spree of cyber attacks on the NHS and major business around the world over the last few weeks.
Their aim was to encrypt the data of their targets and ransom the cypher keys, although it has become pretty clear that the majority did not pay anything.
The disruption caused though was catastrophic, just look at the number of operations that were cancelled by the NHS!
There are several preventative measures that you can put in place to help prevent this kind of attack, and also disaster recovery measures that can get you back to normal as soon as possible.
1. Ensure you have a good anti-virus protection suite installed on your computer, and ensure it is updated regularly.
I personally recommend Avira Security Suite which can be downloaded free from this link avira.com
2. Ensure windows update is set to automatic - although we all know windows updates can be a pain in the proverbials, most updates are security related and it is important that these updates are installed.
3. Be extra careful about what you click on. especially when it attached to an email - most ransomware attacks so far have been attached as a zip file to emails - so beware of anything zip!!
OK - so you get the dreaded screen saying you have been hacked, your data has been encrypted or your web browser behaves very strangely, so what can you do to get going again?
The first rule of using anything digital is to ensure you take a regular backup of all your important data - photographs of the kids growing up, latest VAT returns and all that kind of stuff should always stored in two places.
This can be in the form of usb memory sticks, external hard drives or cloud storage such as google drive. There are many options but they should be separate from your PC as the attack could effect anything attached to the PC as well.
There are various types of backup - you can do a full backup of your PC including a system image which allows you to fully resore your PC using recovery media, or a backup of just your data. In the second case you will need to re-install your operating system before restoring your data.
