SSC CGL Tier II - 19 Jan 2026 - Shift 1 • Computer • Q145

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.
