DoS attacks are categorized as what?

Phishing attacks are social engineering attacks aimed at tricking users into revealing sensitive information, not primarily about overwhelming system resources.

Denial-of-Service (DoS) attacks often involve sending a massive volume of traffic to a target, such as SYN floods or UDP floods, to overwhelm its resources and prevent legitimate users from accessing services.

Virus attacks involve malicious software that replicates and spreads to compromise systems, which is a different category than DoS attacks.

Trojan attacks involve deceptive malware that appears legitimate but performs malicious actions, distinct from the resource exhaustion characteristic of DoS attacks.
