What is the DoS attack created by using zombie computers that makes it difficult to trace the origin?

• A. Distributed DoS (DDoS)
• B. DNS Poisoning
• C. Dial-ups
• D. Diffserv

Answer: (A)

The key idea is a distributed denial of service. When a large group of compromised machines—zombies—are coordinated to flood a target, the attack traffic comes from many different origins rather than a single source. This spread makes tracing the true origin much harder, because there isn’t one easy fingerprint to follow; the attacker hides among a botnet of hosts distributed across networks and countries. The attacker controls all those zombies from a central command, amplifying the impact while concealing who is really behind it. DNS poisoning, on the other hand, tampering with DNS data to misdirect users, and Dial-ups or Diffserv, which relate to different concepts (legacy connection methods and traffic management QoS, respectively), don’t describe a botnet-driven flood aimed at obscuring the origin.
