2. Meaning
• Cybercrime is any criminal activity that involves a
computer, networked device or a network. While most
cybercrimes are carried out in order to generate profit for
the cybercriminals, some cybercrimes are carried out
against computers or devices directly to damage or
disable them, while others use computers or networks to
spread malware, illegal information, images or other
materials. Some cybercrimes do both -- i.e., target
computers to infect them with viruses, which are then
spread to other machines and, sometimes, entire networks.

TOR

7. LAYERS OF INTERNET

8. What is the DARKweb?
 All information that cannot be indexed using
general web search engines
 Also known as the deep internet, deepnet, or the
hidden web

9. Content Found On The Invisible Web
•Private web
•CHILD PONOGRAPHY
••Unlinked content
••Scripted content
••Limited access content
••Databases
•HACKED BANK ACCOUNTS

10. Advantages Of DARK Web
Content
 Specialized content focus – large amounts of
information focused on an exact subject
 Contains information that might not be available
on the visible web
 Allows a user to find a precise answer to a
specific question
 Allows a user to find webpages from a specific
date or time

11. So what is actually on the Deep
Web,
and how do we get there?
Deep Web (layer two)
- Content that is only available through
specialized anonymizing software (Tor). This includes
anonymity networks and darknets (anonymous P2P). This are is
a sort of safe- haven for speech and content which has been
banned from the surface web.
- examples: Anonymous chat/imageboards. CP, drugs,
illegal transactions, weapons, DRM removal software, pirated
software/media/ books, black markets.

12. .onion:
-onion is a domain host suffix designating an anonymous hidden
service reachable via the Tor network.
-The purpose of using such a system is to make both the
information provider and the person accessing theinformation
more difficult to trace, whether by one another, by an intermediate
network host, or by an outsider.
-.onion adresses are 16-character non-mneumonichashes,
compromised of alphabetic and numeric strings.
-The "onion" name refers to onion routing, the technique used by
Tor to achieve a degree of anonymity.
Accessing the Deep Web

13. Accessing the Deep Web
Tor:
-” The Tor software protects you by bouncing your
communications around a distributed network of relays run by
volunteers all around the world: it prevents somebody watching
your Internet connection from learning what sites you visit, it
prevents the sites you visit from learning your physical location,
and it lets you access sites which are blocked.” –
www.torproject.org
-Tor is a network that supports onion routing; a way to
help make your traffic anonymous. Because the Deep Web is
compromised of information that doesn’t show up on search
engines, or has no domain name registry, you must know
exactly where you are going to get there.

14. The first step is to download, install, and run the Tor Bundle. This will bring up your new
anonymous browser (through Firefox) in order to get started.

15. Currency of the Deep Web
Bitcoins:
-an electronic cash system using peer-to-peer networking, digital
signatures and cryptographic proof to enable irreversible payments
between parties without relying on trust. Payments are issued and
transferred by the Bitcoin network.
-Participants begin using Bitcoin by first acquiring a Bitcoin wallet
and one or more Bitcoin addresses. Bitcoin addresses are used for
receiving Bitcoins, similar to how e-mail addresses are used for
receiving e-mail.
-In April 2012, 1 BTC traded at around $4.80. Taking into account
the total number of Bitcoins in circulation, the market capitalization
of the Bitcoin network stands at over 40 million USD

16. Guided Journey Through the Deep Web
The deep web is vast, as we covered before, and most is private.
Here we will go through some examples of websites on the Deep
Web, how online currency works, and the various resources the
Deep Web encompasses (not all entirely legal)
This content can be disturbing. Obviously with great resources such
as free library databases, and banned books, comes information
that is considered scat. Being a safe-haven from the censorship of
the surface web, there is a lot of CP, arms/drug trade, and other
illegal information on the Deep Web. It’s up to you as an individual
to steer clear of what you don’t want to see.
In addition, one must also be skeptical. There are even sites
dedicated to contract killing, but one can’t be sure that these
websites are even serious.

17. The next step is to access the Hidden Wiki, which most people consider the home page of the Deep
Web. Here you can begin your journey and discover many different types of sites and networks,
ranging from tame to very illegal. There are black market type sites, hacking information sites, huge
file databases, political advocacy sites, and even sites to hire people to engage in illegal activity.

18. One of the other “main pages” of the Deep Web is TorDir. TorDir is a site that uses a special
crawler for the Deep Web, so that it may act similar to Google in that it categorizes web sites,
and allows you to view many different and obscure .onion sites that fall into each category.

19. Through the Hidden Wiki you can find pages like this, which are semi-organized lists of different
.onion sites. Many different sites are listed and separated based on function, such as
buying/selling/trading, communication, hacking, or intel exchange.

20. This is an example of one of the many online black markets. This one did not require a
paid membership. There are many different ways to spend bit coins, such as on apparel,
money transfers, drugs, books, and even digital goods.

21. This is an example of someone’s own personal page, with content picked out due to it’s
controversial nature. Here you can find anything from banned readings, to trefelling.
There is content on making one’s own explosives, and many different military type
documents and guidebooks.

22. There is a huge portion of the Deep Web that is not malicious at all. This is a huge
database of banned, black listed, and forbidden books which you can read and
download. Books have been burned in the past and banned for their controversial
subject matter, and this is a way for history to be preserved.

23. Another scholarly database, this .onion site is a compilation of financial, business, real
estate, and even marketing tools and texts free to anyone who wants to download them.
The Deep Web is a great archive for educational material.

24. The Deep Web is full of malicious content. On this Russian-based community hacking
website, one can purchase credit card information, PayPal account information, bank
accounts, and even the service of DDoSing a website. This is when the website is
overloaded with information sent to it, and eventually is forced to shut down.

26. SOME TRUE DARKWEB FACTS

27. DangersoftheDARKWeb
If you decide to look into the Deep Web on your own
volition, make sure to be careful.
-Have anti-virus protection.
-Have a paid vpn
-Be intelligent about what links you click. The
Deep Web is a haven for Phishers.
-If you don’t want to see any disturbing images
or content, simply browse as text-only.
