In light of the current issue that has affected the NHS we thought that it would be wise to issue some guidance.
What is ransomware?
A malicious computer program that is designed to cause in convenience and data loss unless a ransom is paid.
How do I get it?
The same as any other virus or malicious program, you could open an email attachment that is infected, download from a compromised website, share it from an infected USB stick or hard drive. If you already have another virus that could ‘leave the door open’ for others.
Most of these infections are allowed to run because the user allows them, by either opening the attachment, clicking run on the download and not thinking through the consequences of opening something from the unknown. By running you effectively give permission for the virus to run and even your Anti Virus software can’t always stop you doing that.
How do I prevent an attack?
- Think before you click… do you know the sender, are you expecting an attachment?
- Keep your device up to date, Windows updates, Flash, Java etc all need keeping up to date to help protect against attacks.
- Keep your anti virus software up to date.
- Look out for warnings in your web browser about sites, don’t download software from websites that you don’t know. If you are asked to run something, ask yourself why.
- Always keep a backup of your data, either in the cloud, on a separate drive or on your server storage area.
- Speak to your Evolve technician if your just not sure, we’re here to advise and help. All you need to do is ask.
What do I do if infected?
- Power off your machines instantly, the quicker you act the more likely that your data will be safe.
- Do not use your USB stick.
- Do not give any personal information over.
- Contact your technician.
