UK National Cyber Security Center Given Statement On Ransomware
On Friday Biggest Ransomware attack Hits many countries including UK. National Health Service was also got affected.
UK National Cyber Security Center statement as follows,
Since the global coordinated ransomware attack on thousands of private and public sector organisations across dozens of countries on Friday, there have been no sustained new attacks of that kind. But it is important to understand that the way these attacks work means that compromises of machines and networks that have already occurred may not yet have been detected, and that existing infections from the malware can spread within networks.
This means that as a new working week begins it is likely, in the UK and elsewhere, that further cases of ransomware may come to light, possibly at a significant scale.
Our national focus must therefore be on two lines of defence.
The first is to limit the spread and impact of the attacks that have already occurred. Due to broad government and partner efforts, a variety of tools are now publicly available to help organisations to do this. This guidance can be found on our homepage – ncsc.gov.uk – under the title 'Protecting Your Organisation From Ransomware'.
We know already that there have been attempts to attack organisations beyond the National Health Service. It is therefore absolutely imperative that any organisation that believes they may be affected, follows and implements this guidance.
We have set out two pieces of guidance: one for organisations and one for private individuals and SMEs which can be applicable regardless of the age of the software in question. It will be updated as and when further mitigations become available and we will announce when updates have been made on Twitter (@ncsc) and elsewhere.
Secondly, it is possible that a ransomware attack of this type and on this scale could recur, though we have no specific evidence that this is the case. What is certain is that ransomware attacks are some of the most immediately damaging forms of cyber attack that affects home users, enterprises and governments equally.
It is also the case that there are a number of easy-to-implement defences against ransomware which very considerably reduce the risk of attack and the impact of successful attacks. These simple steps to protect against ransomware could be applied more thoroughly by the public and organisations
Companies can undertake three simple steps which are also set out on our website and can be summarised as follows:
- Keep your organisation's security software patches up to date.
- Use proper antivirus software services.
- Most importantly for ransomware, back up the data that matters to you, because you can't be held to ransom for data you hold somewhere else.
Home users and small businesses can take the following steps to protect themselves:
- Run Windows Update
- Make sure your antivirus product is up to date and run a scan – if you don’t have one install one of the free trial versions from a reputable vendor
- If you have not done so before, this is a good time to think about backing important data up – you can’t be held to ransom if you’ve got the data somewhere else.
