As you may have seen in the news recently cyber-attacks against large organisations are becoming more and more common. With the Ransomware attack against Irelands Health Service, really brings to the forefront of the mind that we, as a healthcare provider are among prime targets for these kind of attacks.
One way in which Ransomware can attach our systems is via an email. On emails, criminals can put in links that will take you to a website and start a download or they send it in an attachment that looks like a photo or word document. As an organisation, we scan all emails for potential threats, which is why sometimes you will find a blocked attachment and have to call the IT Service Desk. The drawback with these systems, is they can only scan against known links and disguised documents. The best and most important line of defence is always going to be staff knowledge.
Ransomware is a program which locks all data on your computer rendering it unusable the criminals then demand a payment to unlock the encryption and release your files, however it is advised not to pay. Many of you will have seen first-hand what ransomware can do to our service, as shown with WannaCry.
If you ever receive an unexpected email with attachments or links, please don’t click them and instead forward the email to – Suspect.Emails@ncic.nhs.uk – and await a response, normally you will receive one the next working day.
As always if you do have any queries, feel free to email email@example.com and a member of the team will be in contact.
