Introduction

This is the age of the Internet and everyone who wants to be informed needs to be online. The Internet is a giant web of information and content is used for a variety of purposes nowadays. However, there are many things that the Internet cannot provide. One of these things is privacy. Internet privacy is a thing of the bygone era. Any device that is on the network is unsafe, and nothing is private. A devastating but universal fact! The FBI, the NSA and third-party sophisticated hackers can track and monitor what you do. Though not many of us are concerned with the fact that our data, our files, our location, etc. are not private, a significant chunk of society is wary of it. If you were not protected, it’s not too late, keep on reading to find out how you can prevent this from happening. If you aren’t worried about your privacy, you might be curious about what exactly the dark web is and how you can benefit from it. Or maybe you want to access certain products that are not accessible over regular Internet or offline. Well, you will find a complete guide in this book to help you. If you follow the instructions given in this book correctly, no one will be able to track you, and you will be safe and secure. Thus, this book is a complete and foolproof guide to Dark Web and TOR, and will help you access the world of the Dark Web without any problems.

Introduction to Tor

In simple words, TOR is the short form of The Onion Router. It is a free of cost software that enables the user to communicate anonymously. It can channel Internet traffic through a worldwide network of seven thousand plus free relays, which can keep the location, as well as usage of the user, anonymous. It can keep you safe and can make it difficult to trace you or your Internet activity. So, TOR is a service that allows its users to browse the Internet, send IMs, chat and socialize but anonymously. What makes it different than other forms of the Internet is that it delivers what it promises. The primary purpose of TOR is to keep the personal privacy of the users secure and allow them a free space to conduct their affairs without any form of monitoring or surveillance. It is thus a mode of confidential communication. You must have noticed the icon of the logo of TOR - it is an onion. This is no coincidence. The onion portrays the system correctly; as the form of routing that is done by TOR is called onion routing. It is the encryption of communication protocol stack in the application layer, one under another, thus, forming an onion-like structure. Tor can encrypt almost all major types of data such as IP address, and forward it through a circuit of various randomly selected relays where each relay decrypts only one layer and forwards the remaining ahead. The final layer is decoded at the destination, and thus the information received is concealed and so is the sender's IP address. In general terms, Tor is also called a browser that is used to browse Dark Web. In the next section of this chapter let us have a look at what is Dark Web or Dark Net and how is it different from Surface Web as well as Deep Web.

What is the Dark Web?

Tor is used to access locations on the Dark Web. However, to understand the nature of the Dark Web, it is necessary to figure out what is Surface Web and what is Deep Web. So, let us have a look at these two terms first.

 Surface Web:

 Surface Web is basically whatever your notions of the Web are. It includes social networking sites, shopping sites, search engines, news media, etc. Almost every site that you can access without any additional settings except a regular web browser and active Internet connection is on Surface Web. A basic definition of Surface Web is as follows - It is a web made of various fixed and static pages. These pages are not dependent on a database for content. However, some sites like amazon.com do have connections with the deep web in the form of database. The pages on static web stay on a server waiting for users to retrieve them. Thus, these pages are nothing but HTML files that are static and whose content never change. To update the pages, it is necessary to replace the HTMLfile of the page. All websites with domains such as. .com, .in, .uk, .org, co.in, .net, etc are Surface Website sites. You must have seen various pictures on the Internet representing Surface web and Deep web. One of the most commonly used pictures to represent the above equation is the picture of an iceberg- where the iceberg above the surface of water represents the surface web while the iceberg below the surface represents deep/dark web. Let us now have a look at what Deep Web is.

 Deep Web :

 A simple definition of the Deep Web is all the pages that a search engine cannot find. i.e. these pages are not indexed by the databases of the search engines. There exist a variety of reasons why a search engine cannot access the Deep Web pages. But before we go there, let us first have a close look at Deep Web. Deep Web is the online database and dynamic web pages that a standard search engine like Google or Yahoo cannot access. It is the content and data behind HTML forms. Like Surface web, the Deep web too has many applications such as email, online banking, chat rooms, etc. There are also services such as video chat rooms, various paid services, video on demand, etc. It is estimated that the Deep Web is almost 400 to 500 times larger than the Surface Web. This means it has more than eight petabytes. Compare this with the nineteen terabytes of data present on the Surface Web, and you will realize how huge the Deep Web is. Certain search engines can access Deep Webs. Some of them include Intent, DeepPeep, Deep Web Technologies, Ahmia.fi, and Scirus, etc. Invisible Web or Deep Web is often confused with Dark Web; however, both these terms are different and refer to different things. While it is legal to access information off Deep Web almost all the time, it is not the case with Dark Web. In the next section let us have a look at the Dark Web. 

Dark Web

As said earlier, the Dark Web is often confused with Deep Web thanks to the hidden nature of both the Webs. However, Deep Web and Dark Web are two different things. It is possible to say that the Dark Web is a part of Deep Web, as standard search engines cannot access it as well. However, it is different than Deep Web as the content on Dark Web is often hidden deliberately. It is a network of sites that can be accessed but are hosted anonymously. These sites are inaccessible to standard browsers and browser techniques and often require special software. The Dark Web is an almost untraceable worldwide network that has many uses, which may or may not be legal. The sites on Dark Web are accessible to only those who know what they are looking f0r. The main motive of the Dark Web is anonymity and privacy. This anonymity is Dark Web's boon as well as a curse. The anonymous veil of the Dark Web is often used to conduct a variety of illicit and illegal activities, which is why the Dark Web is so notorious. This notoriety is often carried forward to Deep Web, making it a stigmatized concept as well. However, as made clear above, both the Webs are two different entities. The Deep Web is a simple collection of databases that is not indexed by standard search engines, while the Dark Web is an encrypted network among TOR servers and users. It is just a tiny, albeit very famous part of the Deep Web. In a single line- all Dark Web is Deep Web, however not all Deep Web is Dark Web. The Dark Web is a minuscule part of the Deep Web; it is estimated that it does not even form 0.5% of the Deep Web. However, it is highly popular thanks to its various anonymous and private markets that often trade in illegal products. Now that you know what Deep Web and Dark Web are, you must be wondering why they exist and whether they are needed

Why does the Deep Web exist?

A simple answer to the above question is because we need to hide certain things. For instance, if you have an Internet Banking account, your account details are on the Internet. However, they cannot be accessed by a simple Google search. Thus, your account pages are secure and safe in the Deep Web. Without the Deep Web, it is safe to assume that the Internet would have been much less useful. We would not be able to have social networks, Internet Banking, E-shopping, etc. as these sites store your sensitive data on Deep Web to make them secure. It also exists to store a large amount of data of the corporate world. For instance, many large corporations store their business-related data on Deep Web. This provides them with safety and security. You might be surprised to know that you access Deep Web almost every day. Yes, as said earlier, your social networking accounts, your email, etc. store your personal data on Deep Web, hence whenever you access your email, your bank statement, Twitter DMs, your office intranet, etc. are all a part of Deep Web. However, all of the above things are not always secure, and you are not anonymous on the Surface Web, even if it is connected to Deep Web. This constant need for anonymity and privacy from the governmental surveillance led to the formation of Dark Web.

History of TOR and why it was created ?

TOR is one of the most commonly used software to access the Dark Web. It is almost a fail-proof way of being anonymous. The history of Tor is quite interesting, and it can help people to understand why the need of Tor arose and why it is still relevant. It will come as a surprise that the roots of Tor can be traced back to the United States Naval Research Lab. Employees of the above organization viz. Syverson, Reed and Goldschlag researched ways to protect the intelligence communication in the mid-90s. This was the beginning of Onion routing. Onion routing then moved on to DARPA, and it was enhanced there in the late 90s. Syverson along with Mathewson and Dingledine launched the alpha version of Tor on 20th September 2002. It was then known as The Onion Routing project. A public version was released the next year. A turning point in the history of Tor was when Mathewson, Dingledine, and others created Tor Project in 2006. A non-profit organization runs and maintains Tor. It is a surprising fact that some of the early financiers of the project were Internews, Google, and University of Cambridge, US. International Broadcasting Bureau etc. It also received monetary support from Human Rights Watch. Nowadays, the US government supports the Tor Project financially. So, the Navy created Tor, to hide/protect governmental communications. The purpose has not changed a lot since then, however, the user circle has expanded and now common people like us can use it to safeguard our privacy as well.

Legality of Dark Web ?

One of the most frequently asked questions regarding the Dark Web is its legality, and to be honest, the issue is rather muddled. In this section, I have tried to shed ample light on this topic to clear any confusion associated with it. Before moving on to the topic, please remember that the Deep web does not equal to Dark web. The deep web is anything that is not indexed by any popular search engine and is thus hidden. However, it can be accessed with regular browsers, unlike the Dark web that needs a particular browser or software. The sites on Dark web are built on the public Internet as well; however, they cannot be accessed easily. Browsing the deep web and dark web is not illegal, technically. Unless you are trying to find content that is inherently illegal like child pornography, you are not doing anything illegal. For instance, there exist many websites on the Dark web that proclaim to sell drugs, fake IDs, guns, and weapons. Some also sell stolen goods etc. Browsing such sites is not illegal, you can browse all you want, however, if you buy something from these sites then it is illegal. As the products available on these sites are stolen, you are practically committing theft by buying these goods. Some of the most popular stolen goods available on Dark Web are guns, weapons, drugs, meth, hacked PayPal Cards, fake ID, stolen iPhones, grenades, etc. Dark Web is not inherently illegal. For instance, there are many harmless sites available on the Dark Web like social networking sites, email services, message boards, etc. These sites are not illegal per se, however, if you discuss illicit content over them then your activities can be counted as illegal or problematic. The legality of the Dark Web also depends upon your area and nation. For instance, Dark Web is allowed in the US, however, accessing it in North Korea is illegal. If your nation has an intrusive and regressive government, then the Dark Web can be illegal in your country. In recent times the FBI and other such organizations have blocked many websites on the Dark Web. Most of these sites dealt with illegal and illicit activities such as illegal guns, weapons, drugs, human trafficking, etc. It is not clear whether just visiting these sites is illegal or not; however, it is safe to assume if you do not own one of such sites or do not buy goods from them regularly, you won’t be prosecuted. So, I hope I have answered your question about the legality of Dark Web. Yes, it is not illegal to access the Dark Web, however, it is necessary to understand that the nature and content of the sites that you visit can jeopardize your anonymity and security. I do not recommend purchasing/ selling anything on the Dark Web; neither do I recommend downloading anything from the network. As a safety measure, it is recommended that you avoid all the links that are unlabeled. These unlabeled links are often without any description and can lead you to some honestly horrifying and disturbing content.
