Ransomware - What you need to know

A recent Ransomware attack which has now spread to 150 countries and impacted 10K businesses, here is some information and links to answer any questions you may have.

Over the weekend the NHS and local authorities were targeted with a Ransomware attack which has now spread to 150 countries and impacted 10K businesses, here is some information and links to answer any questions you may have.

What is Ransomware?

Ransomware works either by encrypting the files on a computer / network or by locking a user’s screen. The user is then required to pay a ‘ransom’ to be able to use the computer normally again. In many cases, the ransom amount is quite modest. This is designed to make paying the ransom the quickest and cheapest way to return to normal use. However, there is no guarantee that the key or password (to ‘unlock’ the computer) will be provided after the ransom is paid.

The scale and automated nature of a ransomware attack makes it profitable through economies of scale, rather than through extorting large amounts from targeted victims. In some cases, ransomware has been known to strike the same victim more than once in succession. Attacks are not normally targeted at specific individuals or systems, so infections can occur in any sector or organisation.

What can I do to protect my business?

  • Install system and application updates on all devices as soon as they become available.
  • Install anti-virus software on all devices and keep it updated.
  • Create regular backups of your important files to a device that isn’t left connected to your network as any malware infection could spread to that too.


What can home users and small businesses do 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.
