Main

Description

This is a smurf attack program developed in Go. It is designed for attacking network load by sending data packets over ICMP(type:Echo). The program uses several libraries to process packets, interact with the network, and generate random data.

Important Note

For the program to work correctly, you need to install Npcap. Without it, the program may not work properly.

You can download Npcap from the official Npcap website.

Dependencies

Before running the program, make sure you have installed the following dependencies:

• golang.org/x/sys/windows — for working with the Windows API.
• Go standard libraries:
  • bufio
  • bytes
  • encoding/binary
  • fmt
  • log
  • math/rand
  • net
  • os
  • strconv
  • strings
  • time

To install the golang.org/x/sys/windows dependency, use the following command:

go get golang.org/x/sys/windows

Also, make sure you have Npcap installed. You can download and install it from the official Npcap website.

How to Run Clone the repository:

git clone https://github.com/Batcherss/goSmurfFlood.git

Enter the folder:

cd goSmurfFlood

Install the necessary dependencies (if not already installed):

go mod tidy

Run the program:

go run main.go

Or you can just start

cmd.bat

that will automatic start the main.go

How it works?

A smurf attack is a type of distributed denial-of-service (DDoS) attack in which an attacker exploits a network protocol to flood a target system with traffic, overwhelming it. Here's how it works:

1. Spoofing the Source Address: The attacker sends a ping request (ICMP Echo Request) to a network's broadcast address, but with the source IP address spoofed to be that of the target system.
2. Amplification: When the broadcast address receives the ping request, it replies to all devices on the network. Each device sends a ping response (ICMP Echo Reply) to the target IP address, which is spoofed by the attacker.
3. Flooding the Target: As a result, the target system is bombarded with a large number of ping replies from all devices on the network, consuming its bandwidth and potentially causing it to become unresponsive or crash. This type of attack leverages the amplification of the broadcast address to increase the volume of traffic directed at the target, making it more damaging with fewer resources required from the attacker.

How to use

• Set it up:
  • src ip: (Enter here victim ip)
  • packet size: (There's packet size of sending icmp , preferably up to 1000 bytes)
  • num. of req.: (Number of requests (from 100 to 200 average for routes)

Notes

Make sure you have administrator rights to work with network packets. The program uses Npcap, so be sure to install it before running the program, otherwise, it may not work correctly.
