The Deep Web

What is
Deep Web?

The Advantages
& Disadvantages of
the Deep Web.

+ All information that cannot be accessed via a normal browser.

+ Also called Deepnet, DarkNet, Undernet, or the Hidden Web.

THE DEEP WEB
Programs that search documents for specified keywords or phrases
and returns a list of documents where the keywords were found.

SEARCH ENGINES
HOW SEARCH ENGINES WORK?
* Uses a spider program to fetch as many webpages as possible

* A program called an indexer then reads these webpages and creates an index, storing the URL and important content of webpage

* Each search engine has its own ranking algorithm that returns results based on their relevance to the user’s specified keywords or phrases

THE INVISIBLE WEB
Everything not found by a search engine’s spider program is part of the invisible web

Most webpages on the internet are not indexed by search engines

Some experts estimate that as much as 75% of the entire internet is invisible web content

SPIDER PROGRAMS
Starts by searching heavily used servers and the most popular web pages.

Visits all the links found in the webpages it reads and sends them to the search engine’s indexer in a process called web crawling, which continues automatically.

To be discovered, a webpage must be static and linked to other pages.

All pages that are indexed by a search engine’s spider programs are known as the visible web.

ADVANTANGES ON INVISIBLE 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

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.

GUIDED JOURNEY TO 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 the various resources the Deep Web encompasses (not all entirely legal).

THE HIDDEN WIKI
TorDir (BLACK MARKET)
Silk Road (Anonymous Market Place
BIBLIOTHECA ALEXANDRIA
ONION sITE
CARDERS PLANET
DANGERS OF THE DEEP WEB
Exploring the Deep Web can be dangerous. Always think twice before clicking any returned search links. Because no ruling authority regulates the Deep Web, users enjoy complete anonymity and may partake in illegal activities such as trading copyrighted materials, selling narcotics, circulating child pornography and negotiating for other criminal acts. Exploring a search engine's results may lead you into the Internet's darkest corners, leaving you vulnerable to nefarious characters and sites designed to spread malware or hack your computer.

DISADVANTAGES OF THE DEEP WEB
Deep Web search engines tend to be slower than standard search engines.

Deep Web searches should be reserved for serious, painstaking research, not for simple questions and basic Web surfing.

May also return sensitive personal information from normally restricted databases, creating ethical dilemmas and leaving individuals susceptible to fraud and identity theft.
