Malware, or malicious software, is a harmful computer program intentionally designed to disrupt computers, mobile devices, networks, and other digital systems.
The most common forms of malware include:
- Worms. Standalone malware that replicates itself across different computers.
- Spyware. Collects data from infected devices and sends the info to the hacker.
- Viruses. A program that replicates itself across programs on the target device.
- Ransomware. Encrypts data and demands payment from the victim to restore access.

Malware-based cyber-attacks aim to steal valuable personal data for fraudulent use, disrupt business operations, or advance politically motivated agendas.
