Internet is a medium of communication where millions of people can connect at the same time. It is called the ''network of networks''. The Journey of the internet started in the 1970s but it became accessible to the general public in the early 1990s. By 2020, approximately half of the world population (4.5 billion) are using it. At first, Robert W. Taylor developed ARPANET (an early prototype of the internet). Later Vinton Cerf and Robert Kahn developed the Transmission Control Protocol/Internet Protocol (TCP/IP) technologies. Internet is not owned by a single entity, it is a decentralized medium. However, many argue that tech giants such as Amazon, Facebook, and Google have control over a large part of the internet. Many countries have banned certain parts of the internet via censorship.
Internet
is classified into the Surface web, Deep web, and Dark web.
The surface web is a part of the internet where a user can access any information
from the website at any location and time from google, bing, or any search
engine without permission. It consists of 3%-4 % of the total internet
comprising entertainment websites, news websites, torrents, and other websites
available publically.

The
Deep web is 94%-95% of the internet consisting of online cloud storage like
dropbox, google drive, research papers of universities, databases of
multinational companies and banks, security data, and other such data. It
requires a proper web address or link to access this data. A user is allowed to
collect information with login credentials and step-verification only. The User
ID and the password is available to the employee of the companies and bank to
fetch the data.
The
Dark web has websites that are not indexed on any search engine that can only
be accessed by algorithm, encryption, and onion routing.
A
special browser like Tor (The Onion Router) is used to reach the dark web. Like
an Onion, it has multiple security layers to protect the identity of the host
website and the user's IP address and privacy. The websites listed on the dark
web have .onion as the domain name which opens in
Tor browser only.
Dark web- The dark side
While
the dark web promises privacy to its users, it violates the privacy of others.
Criminal-minded Hackers trade data of PAN, personal photos and videos, social
media and bank account details, location, email ID password, payment through
credit or debit card, and other such information. They sell it on the dark web
to make money out of it. The trading of cryptocurrencies like Bitcoin and Monero has
increased on this platform.

Surfing on the dark web is not illegal. But, it is difficult to find websites on it. A person has to face trouble if he joins forums that include hate speech, smuggling, criminal behavior, etc. Researchers from King's College in London, Daniel Moore and Thomas Rid classified the contents of 2,723 live dark web sites over five weeks in 2015 and found that 57% host illicit material.
The dark web and the deep web are also often considered the same, but, they are not. The dark web is just one part of the deep web. Online banking, payment sites, and file hosting services are all parts of the deep web.
Data leaks
According
to a report published in Security magazine in December 2020, Anurag Sen from Security

As per
the reports published in Firstpost in March 2021, hackers
allegedly leaked data of 9.9 crores of Mobikwik users in India while the
company's CEO Bipin Preet Singh denied the claim. It was exposed by
cybersecurity analyst Rajshekhar Rajaharia and later wrote to the Reserve Bank
of India and payments firms. Mobikwik replied that it will call a third party
to conduct a forensic security audit to provide clarity on this matter. This
leak is considered to be the biggest leak that happened in India. The hackers only
wanted the money without any ill intentions.
Air
India reported a cyberattack that took place in the last week of February 2021,
where the personal data of 45 lakh passengers of Air India got leaked. Hackers
gathered information of the travelers registered between 26th August 2011 to
20th February 2021. Data breach includes the name of the passenger, date of
birth, contact details, passport and ticket information, credit card details,
etc. This cyberattack took place on the SITA passengers service system. SITA is
a Switzerland-based IT company that offers services that includes passenger
online booking system, airport operations, baggage, and transport, etc. It
covers 200+ countries with more than 2500 customers. Air India made a deal with
SITA in 2017 to upgrade its IT infrastructure to enable it to join the star
alliance.
Cybersecurity expert Rajshekhar Rajaharia tweeted to report the data of famous pizza brand Dominos is available on the Dark web for sale. A hacker admitted having gained access to Dominos data of 13 TB which includes payment details. However, Dominos India denied the leak of financial details of the users.
