Malware: malicious software
Lesson details
Learning outcome
I can describe malware and explain how it attacks systems.
Key learning points
- Malware is malicious software designed to harm, steal, or disrupt computer systems.
- There are different types of malware, including viruses, worms, trojans, ransomware, spyware, and adware.
- Each type of malware works differently, but they often trick users into downloading or installing them.
- Malware can cause serious damage, such as data loss, system failure or financial loss.
Keywords
Malware - malicious software - a program designed to cause damage to computer systems, corrupt or change files, steal data or cause disruption to services
Infect - to spread something harmful like a virus or malware into a system
Stealing - the act of taking something that doesn’t belong to you, without permission and with no intention of giving it back
Ransom - the money cybercriminals demand after locking files or systems
Common misconception
Malware only affects computers, not phones or tablets.
Malware can infect any idevice that is connected to the internet, including smartphones, tablets and smart TVs. Mobile malware is increasingly common and can steal data, track location or lock users out of their devices — just like on computers.
Teacher tip
Incorporate storytelling to explain how malware spreads and impacts victims. Turn famous or recent malware incidents into short, engaging stories. Storytelling helps students remember key concepts and see the human side of cybersecurity threats, making lessons more impactful.
