What is the main purpose of a Trojan horse in network and information security?
To steal or delete files and create a backdoor for hackers
A Trojan horse is malware that disguises itself as a legitimate or useful program so that a user is tricked into downloading and running it.
Once the user executes it, instead of performing the harmless task it appears to offer, it quietly carries out malicious actions in the background.
Typical Trojan payloads include stealing or deleting the user's files and installing a backdoor, a hidden entry point that lets an attacker access or control the system later.

Blocking a service by overwhelming servers describes a Denial-of-Service (DoS) attack, and flooding communication channels is likewise a traffic-based attack, neither of which is what a Trojan does.
Silently copying itself to other systems through network vulnerabilities is the defining behaviour of a worm, which self-replicates, whereas a Trojan relies on the user to run it and does not spread on its own.
