The National Cyber Security Centre (NCSC) have published some tips on keeping safe from ransomware. We would like to translate them into plain English and help you understand what you need to do to stay safe from Cyber Crime.
How to prevent a ransomware incident, and what to do if your organisation is infected.
Ransomware is a growing threat to global cyber security and one which may affect any organisation, however large or small if it does not have appropriate defences. In the first half of 2016, there was a threefold increase in ransomware types, compared to the previous year. Ransomware has been a threat to Windows operating systems for many years, but attacks against Mac and Linux systems are also increasingly being seen.
The methods that ransomware uses to infect systems are similar to those used by other malicious software. The steps organisations should take in order to protect themselves are also well-known. Ransomware infection can cause a minor irritation or a wide-scale disruption – depending on the measures your business has taken. Ransomware attacks are not usually targeted at specific individuals, so infections are possible in any organisation.
What is Ransomware?
There are two different types of ransomware; the first will encrypt the files on a computer or your network. The second type will lock the computer’s screen. Both types of ransomware tell users that they must make a payment (a ‘ransom’) if they are to use their computer again. The ransom is usually demanded in an untraceable cryptocurrency, most often Bitcoin.
In many cases, the amount of ransom requested is relatively modest. This is deliberate – the criminals want to make paying the ransom the quickest and cheapest way to restore the computer, so people pay up. However, you should be cautious, as there is absolutely no guarantee that payment of the ransom will actually unlock the computer. The criminals may make further demands after unlocking only some files – and if the software is still on the PC, they can easily strike again.
