Cybercrime series – Malware explained

Reading Time: 2 minutes

Last week Ticketmaster UK admitted it had suffered a security breach, which could have resulted in thousands of customers having personal or payment information stolen.

The breach was caused by malicious software (malware) Ticketmaster discovered on a third-party supplier’s support product.

Ticketmaster UK has alerted the customers whose information may have been accessed, offering them a free 12-month identity monitoring service. Whilst Ticketmaster UK may not have suffered initially from the breach, this service and the damage to its reputation may have a long lasting financial impact.

Cyberattacks and data breaches are becoming increasingly common and it’s not just the big companies who are targeted. To be able to protect your business you should understand the risks so you can implement your own protection.

What is Malware?

Malware is malicious software designed to bring harm to a computer system. It can steal protected data, delete documents or add software not approved by the user. The most common types of malware are:


A computer worm is a standalone computer program that replicates itself in order to spread to other computers. They typically contain code designed to do more than spread the worm, known as the ‘payload’. Typically payloads might delete files, encrypt files or steal data.


Viruses replicate themselves by modifying other computer programs. Much like worms they contain payloads that cause harm by deleting files, stealing data or compromising systems completely.


A Trojan misleads users of its true intent by masking its identity, like the famed wooden horse in the Ancient Greek legend. Once it has accessed the system it can cause harm in any number of ways.


Spyware is software that gathers information about a person or organisation without their knowledge. It may send the information to another entity or asserts control of a device with the user’s knowledge.


Ransomware threatens to publish the victim’s data or permanently block access unless a ransom is paid.

This is not an exhaustive list. There are many more types of malware
