You will no doubt be aware of the ransomware threat currently faced by UK organisations. The National Cyber Security Centre (NCSC) aims to provide advice and guidance and services to help improve the cyber security resilience of organisations in the UK. To help mitigate the threat of ransomware we would recommend that your organisation take the following steps:

·Read this guidance:Mitigating malware and ransomware.

 The NCSC urges all organisations to read and follow our guidance on mitigating malware and ransomware. This advice was updated in March 2021 and details a number of steps organisations can take to disrupt ransomware attack vectors and enable effective recovery from ransomware attacks. This includes a wide arrange of actions that you can take to minimise the impact of a ransomware attack. We appreciate that acting on all the recommendations could be an involved operation, so if you want to do something right now, we recommend that you consider the steps below in the first instance.

·Back up your key data         

What would you do if your business files were lost to ransomware? To get back up and running we recommend Offline Backups, this will enable quick restoration of business functions. Good backups make getting back to business quicker with less long-term impact. In addition to encrypting files on your computers, ransomware attackers will often attempt to corrupt or alter existing backups. Offline backups are your best defence and will mean encrypted devices can be wiped and restored from Offline backups.

Offline backups (cloud or disconnect physical media) are when the data can be protected from accidental or malicious deletion, they also should offer version retrieval. If you lose access to your files due to ransomware you should protect against this by recovering from an earlier version if a backup has been completed since the attack and preventing deletion of backups.

We recommend that you follow the blog on offline backups

·Disable Remote Desktop Protocol (RDP) – where possible….

RDP account compromise is the source of 50% of ransomware attacks. Where possible we suggest you turn off RDP. In order to do that you need to understand if you have it. NCSC’s Early Warning service will help you know and provide many other benefits. If you identify RDP and didn't know it was on turn it off.

If you have to use RDP we recommend using Multi-Factor Authentication and following the guidance Make sure you follow the principles of Privileged Access Management (PAM)" )" &

Make sure that the accounts that are allowed to use it have unique passwords - try #3randomwords
