Show answer & explanation
Correct answer: C
Concept
Malware is classified by its primary behaviour and delivery model. Ransomware encrypts or locks data to demand payment; a worm self-propagates across systems; a Trojan appears as legitimate software; and spyware covertly monitors or extracts information.
Application
WannaCry is ransomware because its payload encrypted files and demanded payment.
Stuxnet is a worm because it could spread between systems while targeting industrial control software.
Emotet is classified as a Trojan; it began as a banking Trojan and was later used to deliver other malware.
Pegasus is spyware designed for covert surveillance and extraction of data from mobile devices.
Cross-check
Checking each example against the defining behaviour gives the one-to-one mapping below.
Malware example | Defining type | Behavioural cue |
|---|---|---|
WannaCry | Ransomware | Encrypts files and demands payment |
Stuxnet | Worm | Self-propagates between systems |
Emotet | Trojan | Masquerades as software and delivers other malware |
Pegasus | Spyware | Conducts covert surveillance and extracts data |
Result
Therefore, the matching is WannaCry-IV, Stuxnet-II, Emotet-I, and Pegasus-III.
