Malware (Glossary)

The term malware belongs in the fields of cybercrime and cybersecurity, as well as digital society. Malware is short for „malicious software.“ It describes programmes that are secretly installed on computers, tablets, or smartphones to cause damage or steal data.

Malware can get onto a device, for example, as an email attachment, via fake websites, or by downloading unsafe apps. A typical example is the so-called „virus“ attack: a user opens an attachment in a deceptively real email, unaware that it contains malicious software. As soon as the file is opened, the malware infects the device, can collect data, and spread further unnoticed.

The consequences of malware are diverse: passwords, personal data, or even company secrets can be stolen, computers can be rendered unusable, or hackers can extort money for the release of blocked data. Malware is therefore one of the biggest threats to digital security – for both private individuals and businesses. Regular updates, strong passwords, and conscious handling of unknown links and attachments offer protection.
