How To Perform a DDOS Attack in 3 Simple Steps?



Introduction

Today, Jane is planning to see a movie on Netflix. When he tried opening, he found that he cannot access the website properly. “Why is it taking too much time to load?” - Jane thought over. Well, it is because of the DDoS attack! Do you know, websites are often attacked and might go offline due to DDoS attacks? Wondering what is DDos or what is the DDoS attack or is it ethical to know how to perform DDoS attacks or steps for DDoS mitigation? The following has all your answers along with an explanation on how to perform a DDoS attack. The article is a complete DDoS how to or a DDoS tutorial for beginners.

What is DDoS Attack?

Endlessly looking for what is the DDoS attack? Distributed Denial of Service or DDoS, in short, is an attempt to make an online help inaccessible by overpowering it with traffic from various sources. They focus on a wide assortment of significant assets, from banks to news sites, and present a significant challenge to ensure individuals can distribute and get to significant data.

What is DDoS?

DDoS is flooding the target with a constant flood of traffic.

Read: Ethical Hacking Tutorial Guide for Beginners

Let us take an example to understand what is the DDos attack in-depth. We have a web server that belongs to a company that sells its products over the internet. Over here, we have a couple of customers with its computers that are browsing the company’s website looking at the company’s products and services. Let’s assume that someone wants to attack this company’s web server. To attack, the intruder will use the company’s computer and the program to attack the web server and flood it with data traffic to try and disrupt its service. This is just a DoS (Denial of Service) attack because the DoS attack comes from one source only. In DoS, the network or server can handle an attack from a single source as it is easier to pinpoint. The server can simply close the connection from where the attack is coming from. DoS attack is easy to handle and is not a big problem. The problem arises when the attack comes from multiple sources simultaneously, and that is what a DDoS is! It is an attack from multiple resources all at once. Now you know what is DDoS attack finally!

DoS (Denial of Service) attack

DDoS (Distributed Denial of Service) attack

So, the intruder’s single computer can communicate with other computers around the world and coordinate an attack on the target server. Thus, the targeted server now has to deal with multiple sources (computers) instead of one. It will overwhelm the server and system resources such as the CPU and memory. It will also erupt network bandwidth. As a result, all the company’s systems will be gone to denial of service because the server is too occupied in dealing with the DDoS attack. So, the webpages these computers want to access will either be moved to the load or will become very slow in loading.

Is this a complex explanation of the DDoS attack? Don’t worry, we have a simple example for you. How about traffic jams?

Read: Ethical Hacking Tutorial Guide for Beginners

The above picture shows the traffic jam as far as you can see. We are not going to test your driving skills, but the definition of DDoS you are looking for is inside this image only!

You check your GPS traffic report, just to see that the jam stretches out for miles and there's no chance to get around it. It is highly unlikely you'll make it to the recreation center in time for your outing. That is essentially what an appropriated DDoS attack is – bunches of users (for this situation, vehicles) that are jamming up a system (the roadway) to deny you from getting to assistance (the recreation center). Normally when we talk about DDoS attacks, the asset being denied is a site and the "congested road" was noxiously brought about by a programmer. But the concept is equivalent to a congested road on the interstate.

How do the attackers get involved in a DDoS attack? How DDoS is performed?

The simple answer to this question is by simply using malicious software. The attacker or the intruder will develop malware and distribute it over the internet and put it on websites or email attachments.

Thus, if a vulnerable computer goes to these infected websites or opens these infected email attachments, the malware will be installed on their computer without the knowledge of the owner that the computers have gone infected or without knowing that their computers have been recruited in an army of other infected systems to perform a DDoS attack. This army of affected computers is known as a botnet. This botnet can be even hundreds or thousands of computers that are scattered all over the world. This botnet is controlled like an army waiting to receive instructions from the attacker. The attacker gives the command to the botnet to attack on a certain date and on a certain time. Once the set time is reached the attack begins!

How the attackers get involved in a DDoS attack? How DDoS is performed?

A DDoS attack can last for an hour or even days. It just depends upon the intender’s intent. Indeed, a review by Kaspersky Lab uncovered that one out of five DDoS attacks can keep going for a considerable length of time or even weeks, bearing witness to their refinement and genuine danger presented to all organizations.

The impact of the attack is that during that, no workers can get access to the network resources, and on account of Web servers running eCommerce locales, no buyers will have the option to buy items or get help. The dollar figure fluctuates, however organizations can lose $20,000 every hour in case of an effective attack.

The impact of the attack

DDoS attacks are surprisingly cheap and easy to initiate, that is, one can easily slow down any website anywhere in the world by buying its cheap services. Slow and independent sites are at particular risk. Because the relative flood of traffic can be taken offline as they don’t tend to have resources or infrastructure to defend themselves. Intruders take advantage of this vulnerability by using DDoS attacks to influence political events and some opposing media.

Steps on how to perform a DDoS attack:

Steps to perform a DDoS attack: 

Stage 1: Creating the Botnet

To create a botnet, a hacker needs an approach to assume responsibility for a great many gadgets — these could be PCs, cell phones, or IoT gadgets, for example, webcams or brilliant fridges. There are many ways the hacker could discover and assume responsibility for these gadgets. For instance, they may compose an infection that proliferates and progressively assumes control over an ever-increasing number of PCs. Or on the other hand, they may locate a particular IoT gadget with known helplessness (for instance, poor default login security) and construct a bot to examine the web and hack however many of those gadgets would be prudent.

Stage 2: Controlling the Botnet

As the programmer assumes responsibility for every gadget, they'll accomplish something so it will comply with any directions the programmer sends to the gadget. (For instance, installing a small program on it.) There are a couple of various methodologies the programmer can utilize (customer server model, P2P model dependent on advanced endorsements, and so on.), yet the final output is the equivalent — the hacker can give an order and every one of the gadgets in the botnet will do whatever the hacker educated them to do.

Stage 3: Executing the Attack

Once the hacker has a huge number of gadgets available to him no matter what, he can execute the DDoS attack. There are a couple of various kinds of DDoS attacks (read them below). However, the essential thought is the equivalent: flood a web server with a larger number of solicitations than it can deal with. The aggressor will normally inquire about the objective site cautiously to distinguish a shortcoming to abuse, at that point create a solicitation that will focus on that powerlessness. At last, the assailant will train their zombie PCs to execute that solicitation (more than once). Here's a model: Let's say John's botnet has 100,000 gadgets in it. He gives an order to the botnet to send an HTTP solicitation to example.com once every second. That is 60 visits for each moment times 100,000 gadgets. That signifies 360 million visits for every hour or 8.6 billion visits for every day. That is definitely more than most web servers are intended to deal with. If the assault was arranged well, the web server will be over-burdened and any genuine individuals who attempt to visit the webpage will get a blunder message. DDoS assault achievement!

DDoS attack symptoms

The symptoms of DDoS assaults include:

  • The site is reacting gradually
  • The site is lethargic
  • The client has issues getting to the site

Any kind of interruption, contingent upon your setup, can be crushing to your business.

Types of DDoS Attacks

Now we know what is the DDoS attack, let’s move further to DDoS types. DoS/DDoS attacks are basically of 3 types-

Types of DDoS attacks

Application layer DDoS attack

Application-layer DDOS attacks are the type of attacks that target Windows, Apache, OpenBSD, or other software vulnerabilities to play out the attack and crash the server. 

Protocol DoS attack

A protocol DDoS attack is a DoS attack on the convention level. This class incorporates Synflood, Ping of Death, and that's only the tip of the iceberg. 

Volume-based DoS attack

This sort of attack incorporates ICMP floods, UDP floods, and other sorts of floods performed by using mock bundles.

“More than 2000 daily DDoS attacks are observed worldwide”

Read: What is the Cyber Security Future in Year 2020?

Obviously, there's a bigger number of ways than the ol' DDoS to hinder a site! There is a large group of other mainstream apparatuses and systems to execute a DoS attack, regardless of whether DDoS is by a long shot the most widely recognized.

  • Teardrop attacks that send disfigured IP addresses and larger than usual information bundles to the objective computer to either back them off or crash them when they attempt to understand it.
  • Banana attacks make an input circle by driving every single active message an objective conveys once again into the objective, which causes more messages, and makes everything insane.
  • Smurf attacks exploit misconfigured organized gadgets to send gigantic documents to each associated gadget on the double, exploding the system.
  • PDoS (or Permanent Denial of Service) attacks include hacking into IoT gadgets and supplanting firmware with something degenerate or deficient.
  • Nukes include sending degenerate blunder messages or operational data information to the objective, backing it off until it's solidified.
  • Peer-to-peer attacks have hackers breaking into an objective system and teaching all the connected devices to attempt to connect with a solitary site or server simultaneously.
  • Ping floods requires you to send countless pings starting with one PC then onto the next - a basic assault and a typical device when cheating in web-based.
  • Degradation-of-service attacks have botnets attack a site in "waves", so the site doesn't close down completely, just backs off as often as possible and capriciously.
  • HTTP POST attacks are an out of date assault strategy that includes sending objective information, however communicating it so gradually that other information needs to 'pause' for it to complete before going.
  • Denial-of-Service Level 2 attacks stunt an objective's protection system from obstructing the system from the web, taking everything disconnected.
  • The Ping of Death is a pernicious, deformed ping bigger than 65,535 bytes, which makes a few frameworks crash when they attempt to deal with it.
  • Amplification attack controls freely open DNS to send DNS traffic to ill-equipped destinations, similar to a greater adaptation of a reflector attack.
  • Slowloris (or RUDY: R-U-Dead-Yet) attempts to hoard however many associations with a site or administration as could be allowed for whatever length of time that they can, to restrain accessibility to genuine clients.
  • Shrew attacks focus on the TCP (Transmission Commission Protocol) with speedy eruptions of action to misuse brake systems and hinder genuine traffic.

Is it legal to perform DDoS?

In principle, no. Practically speaking… yes…

Essentially, playing out a DoS attack on any association or site is viewed as a wrongdoing, although not a horribly terrible one. In most  cases, it'll get you about a year in jail and a hefty fine. If the DoS attack you have committed something genuine (like, say, you are one of the people at police headquarters), at that point different charges could be hurled over those. There have been individuals who've contended that it ought to be a genuine type of dissent, yet all around, getting discovered DoSing will bring you inconvenience in the US and UK.

However, practically speaking, the legitimateness of DoS attacks is not yet decided. To be specific, governments can and have utilized DoS attacks previously as a type of digital fighting, and associations can target themselves with DoS attacks to test server limit as well as their cybersecurity group. So while you shouldn't do DoS attack in any case, simply realize that getting captured will likewise get you in a difficult situation.

Let’s do a DDoS hacking activity!

To perform this activity, you need to use your Windows OS. Also, you need at least two systems that are on the same network. DDoS attacks cannot be performed illegally so you are required to setup your network so that you are authorized to perform this exercise (better to learn LAN).

Let’s begin!

  1. Open command prompt on the target computer
  2. Enter command “ipconfig”. You will get the following screen:DDoS hacking
  3. Now, switch to the system that you want to use for the attack and again open command prompt
  4. We will ping our injured individual PC with interminable information parcels of 65500
  5. Enter the command- Ping 10.128.131.108 –t |65500 
    • "ping" sends the information bundles to the person in question
    • "10.128.131.108" is the IP address of the person in question
    • "- t" signifies the information parcels ought to be sent until the program is halted
    • "- l" indicates the information burden to be sent to the person in question
  6. You will get results like the ones demonstrated as follows-DDoS hacking
  7. Flooding the target PC with data packets doesn't have a lot of impact on the person in question. All together for the attack to be increasingly successful, you should attack the target PC with pings from more than one PC.
  8. The above attack can be utilized to aggressor switches, web servers and so on.
  9. In the event that you need to see the impacts of the assault on the objective PC, you can open the errand supervisor and view the system exercises.
    • Right click on the taskbar
    • Select start task manager
    • Click on the system tab
    • You will get results like the accompanyingDDoS hacking

If the attack is successful, you ought to have the option to see increased network activities.

How to protect yourself from DDoS attacks?

“1 out of 3 downtime incidents are attributed to DDoS attacks”

DDoS attack can cause server blackouts and money related loss and spot stress on IT experts attempting to bring assets back on the web. The correct location and aversion techniques can help in DDoS mitigation, before it increases enough energy to topple organization systems. Moreover, contact your network manager to affirm whether the administration blackout is because of support or an in-house network issue. Network administrators can likewise monitor traffic to affirm the nearness of an attack, distinguish the source, and relieve the circumstance by applying firewall rules and potentially rerouting traffic through a DoS protection service. Additionally, contact your ISP to inquire whether there is a blackout on their end or whether their server is the target of the attack and you are a backhanded injured individual. They might have the option to educate you on an appropriate matter with respect to the activity to help with DDoS mitigation.

There is another option to protect yourself from DDoS attack, get knowledge of how cybersecurity is affected. It is said, “To beat the devil, you need to become the devil”. But yes, the positive one! If you want to learn more strategies like this, you can learn ethical hacking, where you can have great comprehension on what is the DDoS attack, how to perform DDoS attack, steps to help with DDoS mitigation, in short it will be a complete DDoS how toHappy learning!
