Distributed denial-of-service (DDOS) attacks on Internet sites are typically evoked by hackers using which of
the following?

A.
Logic bombs

B.
Phishing

C.
Spyware

D.
Trojan horses

Explanation:
Trojan horses are malicious or damaging code hidden within an authorized computer program. Hackers use
Trojans to mastermind DDOS attacks that affect computers that access the same Internet site at the same
moment, resulting in overloaded site servers that may no longer be able to process legitimate requests. Logic
bombs are programs designed to destroy or modify data at a specific time in the future. Phishing is an attack,
normally via e-mail, pretending to be an authorized person or organization requesting information. Spyware is a
program that picks up information from PC drives by making copies of their contents.
