The NHS today confirmed that many Trusts have been hit by a large scale Cyber attack, locking staff out of their computers and causing many to have to move Emergency patients.
IT Systems of many NHS Trusts across the country seem to have been hit simultaneously Encrypting crucial files and demanding a Ransom for access. NHS Digital have reported that as of 15:30 16 Trusts have been affected by this issue and there is currently no evidence to suggest Patient files have been accessed.
The way these Ransomware attacks work is by simply locking the data on an infected system via Encryption and demanding a ransom for the Key to unlock. No data is moved from the system (typically).
So what can be done to prevent or restore systems after these attacks? Well a lot actually and we’d be lying if we said this wasn’t a weekly occurrence for our engineers to deal with. While a lot of companies don’t have a backup plan many are not implemented properly or robustly. And to make matters worse with the rise of products like Dropbox and Google Drive many believe this serves as a suitable backup of Data, well in this instance they too would be rendered useless.
Many organisations believe that a backup implemented years ago is still running and backing up their files, we have found around 70% are no longer operating and backup errors are going un-noticed.
These Ransomware attacks are becoming more common and will soon be commonplace, it really is time to invest in a suitable backup technique and the best news is it’ll probably only cost £10 per month.
