What type of DDoS attack uses UDP packets?

The correct answer is Fraggle, which is a type of Distributed Denial of Service (DDoS) attack that exploits the User Datagram Protocol (UDP). In a Fraggle attack, the attacker sends a large volume of UDP packets to a device, typically a broadcast address. When the target device receives these UDP packets, it broadcasts them to all devices on the network, amplifying the traffic and causing a denial of service for legitimate users.

This attack relies on the inherent nature of UDP, which is a connectionless protocol. Unlike TCP, which establishes a connection before data transfer, UDP sends packets without checking for successful receipt, making it easier to flood a network with traffic. The Fraggle attack is often used in conjunction with amplification techniques, whereby the original small request leads to a much larger response, overwhelming the target's resources.

In contrast, other options like SYN Flood and Smurf involve different types of protocols and methods of attack. SYN Flood attacks primarily leverage TCP connections to exhaust server resources, while Smurf attacks typically utilize ICMP packets rather than UDP. Pharming, on the other hand, is not a network flood attack but rather a method of redirecting users to malicious sites through DNS manipulation. Thus, the distinctive use of UDP packets
