Sample Questions

Question 1

What type of malware disguises itself as legitimate software to trick users into installing it, but does not self-replicate?

Answer: A Trojan horse. Unlike viruses or worms, Trojans rely on user interaction to execute and do not spread on their own.

Question 2

What is ransomware, and what is its primary objective?

Answer: Ransomware is malware that encrypts a victim's files and demands payment (ransom) in exchange for the decryption key.

Question 3

What type of malware embeds itself into a host file and requires that host file to be executed in order to spread?

Answer: A virus. It attaches to legitimate programs or files and activates when the infected file is run.

Question 4

What is a rootkit, and why is it particularly dangerous?

Answer: A rootkit is malware that gains administrator-level (root) access and hides its presence from the OS, making it extremely difficult to detect and remove.

Question 5

What distinguishes a worm from a virus?

Answer: A worm self-replicates and spreads across networks without needing a host file or user interaction, while a virus requires a host file and typically needs user action to spread.
