Ransomware is a type of malware that prevents you from accessing your computer (or the data that is stored on it). The computer itself may become locked, or the data on it might be stolen, deleted or encrypted. Some ransomware will also try to spread to other machines on the network, such as the Wannacry malware that impacted the NHS in May 2017.
How does ransomware work?
Access - Attackers gain access to your network. They establish control and plant malicious encryption software. They may also take copies of your data and threaten to leak it.
Activation - The malware is activated, locking devices and causing the data across the network to be encrypted, meaning you can no longer access it.
Ransom demand - Usually, you will then receive an on-screen notification from the cybercriminal, explaining the ransom and how to make the payment to unlock your computer or regain access to your data.
It is important to try and establish how the attackers gained access to your network in the first place so you can prevent future ransomware attacks.
How can I protect my business or charity from a ransomware attack?
Always back up your data, as restoring your files from a backup is the quickest way to regain access to your data.
Never click on unverified links, especially when they are from sources or senders that you don’t recognise.
Regularly scan your emails and systems for malware
Only download files from trusted sites
Use a VPN when using public Wi-Fi.
Do not use unfamiliar USB devices.
