Types of Malware

Question 1

Malware

Answer 1

Software designed for malicious purposes or malicious software. It can be hidden in a computer program, a piece of code, and even embedded in hardware.

Question 2

Virus

Answer 2

This is a self-replicating software that targets systems in a computer and attaches itself to them upon execution. As a virus spreads across a computer, it may corrupt or destroy data and cause a lot of damage.

Question 3

Worm

Answer 3

Similar to a virus, a worm self-replicates but does not require user intervention for it to be executed. It can spread to other computers, typically over a network.

Question 4

Trojan Horse

Answer 4

Code that masquerades as a legitimate program but causes a lot of damage when executed. Trojan horses do not self-replicate like worms or viruses. They can, however, create backdoors in systems or use system resources for various purposes, such as crypto mining.

Question 5

Spyware

Answer 5

Malware that attempts to harvest information from a computer. The possibly confidential information is copied to the attacker’s computer.
