Ethical Hacking Essentials Practice Test

Identify the attack technique where an attacker performs spoofing using multiple intermediary machines.

1. Permanent Denial-of-Service Attack

2. Distributed Reflection DoS Attack

3. UDP Flood Attack

4. SYN Flood Attack

The correct answer is: Distributed Reflection DoS Attack

The correct answer pertains to the Distributed Reflection DoS Attack, a technique where an attacker exploits the functionality of multiple intermediary machines to amplify the attack against a target. In this scenario, the attacker sends a request to various systems, which then respond to the target's network, overwhelming it with a flood of traffic. This method utilizes the resources of multiple systems to generate a high volume of traffic, making it more difficult for the target to mitigate the attack effectively due to the decentralized nature of the assault. This type of attack also leverages the concept of IP address spoofing, as the responses from the intermediary machines appear to come from the victim's address rather than the attacker's, further obfuscating the origin of the attack and complicating the defensive measures that must be employed. The use of multiple intermediary machines is crucial as it enhances the scale of the denial-of-service effect, leading to significant disruptions for the targeted organization. In contrast, the other options represent different types of malicious activities that do not specifically involve using multiple intermediary machines for spoofing. A Permanent Denial-of-Service Attack seeks to make a service permanently unavailable, while a UDP Flood Attack and SYN Flood Attack both involve overwhelming a target with traffic but do not specifically employ multiple intermediary systems to amplify
