What is the main purpose of a Trojan horse in network and information security?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4, i.e., to steal or delete files and create a backdoor for hackers.
A Trojan horse is a type of malicious software that:
- Appears legitimate to trick users
- Once installed, it can:
- Steal sensitive data (passwords, files)
- Delete or modify files
- Create a backdoor for hackers to access the system remotely
Unlike worms or viruses, Trojans do not self-replicate.
