Ransomware for business

Ransomware is a type of malicious software (malware) that makes your computer or its files unusable unless you pay a fee.

Ransomware is a financially-motivated crime – criminals get individuals and organisations to pay by holding their information to ransom.

Use this guidance to learn about how to protect your business from ransomware.

Tip: Proactively protect your business from ransomware by creating regular backups of files that are important to your business and storing them offline.

Ransomware is one of the most frequent and damaging types of malware affecting businesses today. It can affect both individuals and organisations alike, and can impose significant costs – in both recovery and down-time. It doesn’t matter how big or small your business, or whether you hold valuable information, the aim is to stop you from accessing the files that matter to you.

Typically, ransomware works by locking up – or encrypting – your files so that they can no longer be used, and some types are even designed to stop your computer from working entirely!

Warning: We recommend that you do not pay the ransom if affected by ransomware. There is no guarantee that paying the ransom will fix your computer, and it could make you vulnerable to further attacks. Restore your files from backup and seek technical advice.

Protect your business from ransomware

Ransomware infects computers in the same ways as other types of malware – for example, attached to or linked from a malicious email, hiding on malicious websites or pretending to be useful applications on peer-to-peer networks.

The same advice to protect your business against malware applies to ransomware, but the key way to reduce the impact of a ransomware incident is to create regular backups of your important files.

Take the following steps to significantly reduce the risk that your business will be impacted by ransomware or other malware:
