A UDP Fraggle Attack is a type of Distributed Denial of Service (DDoS) attack. It involves sending a large amount of spoofed UDP traffic to a network’s broadcast address. This causes all devices on the network to respond to the spoofed address, overwhelming the target with traffic and potentially causing it to become unresponsive.
Example of a UDP Fraggle Attack:
1. Attacker: Sends a large number of UDP packets with a spoofed source address (the address of the victim) to the broadcast address of a network.
2. Broadcast: The network’s broadcast address forwards these packets to all devices on the network.
3. Response: Each device on the network responds to the spoofed source address (the victim), creating a flood of traffic directed at the victim.
4. Impact: The victim’s network or device becomes overwhelmed by the sheer volume of responses, leading to a denial of service.
This attack is similar to the Smurf attack, but instead of using ICMP (Internet Control Message Protocol) packets, it uses UDP (User Datagram Protocol) packets.
