Which specific attack uses spoofed UDP packets to random ports at a high rate from multiple source IPs?

• A. ICMP flood attacks
• B. UDP flood attack
• C. Ping of Death
• D. DoS attack

Answer: (B)

This describes a UDP flood attack, a DoS technique that relies on sending a massive number of UDP packets to the target. Because UDP is stateless, the sender can spoof source IP addresses and target random destination ports, which helps overwhelm the target’s network and services while making it hard to trace the source. Flooding with packets at many ports ensures that the target’s resources and socket handling are consumed, increasing the likelihood of disruption.

The other options don’t fit as precisely. An ICMP flood uses ICMP packets (pings), not UDP, so the spoofed, port-randomized UDP behavior isn’t involved. Ping of Death is a historic attack that abuses oversized ICMP packets, not UDP, and is not about high-rate UDP traffic to random ports. A DoS attack is a general category, but the description specifies a particular method (UDP floods with spoofing and random ports), which is what makes UDP flood the best match.
