This repository contains a Go application designed to create and send UDP packets with a raw socket. It's intended for educational purposes to understand network protocols and raw socket programming in Go.

This tool is provided for educational purposes only. Any misuse of this software will not be the responsibility of the author or of any affiliates. The end-user is solely responsible for complying with all applicable laws and regulations in their jurisdiction.

• Go 1.20
• Root or Administrator privileges (for raw socket operations)
• Wireshark (for packet analysis, optional)

Clone the repository to your local machine:

git clone https://github.com/araujo88/GoUDPflood.git
cd GoUDPflood

To run the application, use the following command:

sudo go run main.go <destination IP> <port number> <data payload>

Replace <destination IP>, <port number>, and <data payload> with the appropriate values.

Example:

sudo go run main.go 127.0.0.1 8080 "Hello, World"

• UDP packet crafting with customizable payload.
• IP and UDP checksum calculation.
• IP header inclusion with the IP_HDRINCL option.
• Spoofed source IP address generation.

The application crafts a UDP packet with a manually constructed IP header, followed by a UDP header and a data payload. It sets the IP_HDRINCL socket option to signal the kernel that the packet will include the IP header. The checksums for both IP and UDP headers are calculated to ensure the packet's integrity.
