Over the last decade, malicious software has become a huge digital threat.

‘Malware’ describes many forms of hostile software including viruses, worms, trojan horses, spyware, and hacktools, and at first these early infectious programs were written as experiments or pranks.

But as internet access became ubiquitous, the motives shifted, and most now target individuals and organisations for illicit purposes. They can take control of your computer, stealing everything from passwords to credit card information.

This visualisation is based on 25 years of data from online security giant Symantec. It maps every detected threat, highlighting the frequency of attacks and how they deceive us to exploit our private information.
