DEEP WEB

The Deep Web (or Invisible web) is the set of information resources on the World Wide Web not reported by normal search engines.

According several researches the principal search engines index only a small portion of the overall web content, the remaining part is unknown to the majority of web users.
What do you think if you were told that under our feet, there is a world larger than ours and much more crowded? We will literally be shocked, and this is the reaction of those individual who can understand the existence of the Deep Web, a network of interconnected systems, are not indexed, having a size hundreds of times higher than the current web, around 500 times.

Very exhaustive is the definition provided by the founder of BrightPlanet, Mike Bergman, that compared searching on the Internet today to dragging a net across the surface of the ocean: a great deal may be caught in the net, but there is a wealth of information that is deep and therefore missed.

Ordinary search engines to find content on the web using software called "crawlers". This Deep Web technique is ineffective for finding the hidden resources of the Web that could be classified into the following categories:

• Dynamic content: dynamic pages which are returned in response to a submitted query or accessed only through a form, especially if open-domain input elements (such as text fields) are used; such fields are hard to navigate without domain knowledge.

• Unlinked content: pages which are not linked to by other pages, which may prevent Web crawling programs from accessing the content. This content is referred to as pages without backlinks (or inlinks).

• Private Web: sites that require registration and login (password-protected resources).

• Contextual Web: pages with content varying for different access contexts (e.g., ranges of client IP addresses or previous navigation sequence).

• Limited access content: sites that limit access to their pages in a technical way (e.g., using the Robots Exclusion Standard, CAPTCHAs, or no-cache Pragma HTTP headers which prohibit search engines from browsing them and creating cached copies).

• Scripted content: pages that are only accessible through links produced by JavaScript as well as content dynamically downloaded from Web servers via Flash or Ajax solutions.

• Non-HTML/text content: textual content encoded in multimedia (image or video) files or specific file formats not handled by search engines.

• Text content using the Gopher protocol and files hosted on FTP that are not indexed by most search engines. Engines such as Google do not index pages outside of HTTP or HTTPS.

A parallel web that has a much wider number of information represents an invaluable resource for private companies, governments, and especially cybercrime. In the imagination of many persons, the Deep Web term is associated with the concept of anonymity that goes with criminal intents the cannot be pursued because submerged in an inaccessible world.

As we will see this interpretation of the Deep Web is deeply wrong, we are facing with a network definitely different from the usual web but in many ways repeats the same issues in a different sense.

What is a Tor? How to preserve the anonymity?

Tor is the acronym of "The onion router", a system implemented to enable online anonymity. Tor client software routes Internet traffic through a worldwide volunteer network of servers hiding user's information eluding any activities of monitoring.

As usually happen, the project was born in military sector, sponsored the US Naval Research Laboratory and from 2004 to 2005 it was supported by the Electronic Frontier Foundation.

Actually the software is under development and maintenance of Tor Project. A user that navigate using Tor it's difficult to trace ensuring his privacy because the data are encrypted multiple times passing through nodes, Tor relays, of the network.

Once inside the network, where it possible to go and what is it possible to find?

Well once inside the deep web we must understand that the navigation is quite different from ordinary web, every research is more complex due the absence of indexing of the content.

When you are going too deep....

A user that start it's navigation in the Deep Web have to know that a common way to list the content is to adopt collection of Wikis and BBS-like sites which have the main purpose to aggregate links categorizing them in more suitable groups of consulting. Another difference that user has to take in mind is that instead of classic extensions (e.g. .com, .gov) the domains in the Deep Web generally end with the .onion suffix.

Following a short list of links that have made famous the Deep Web published on Pastebin.

Cleaned Hidden Wiki should be a also a good starting point for the first navigation. Be careful, some content are labeled with common used tag such as CP= child porn, PD is pedophile, stay far from them.

The Deep Web is considered the place where every thing is possible, you can find every kind of material and services for sale, most of them illegal. The hidden web offers to cybercrime great business opportunity, hacking services, malware, stolen credit cards, weapons.

We all know the potentiality of the e-commerce in ordinary web and its impressive growth in last couple of years, well now imagine the Deep Web market that is more that 500 times bigger and where there is no legal limits on the odds to sell. We are facing with amazing business controlled by ciber criminal organizations.

Speaking of dark market we cannot avoid to mention Silk Road web site, an online marketplace located in the Deep Web, the majority of its products are derived from illegal activities. Of course it's not the only one, many other markets are managed to address specify products, believe me, many of them are terrifying.

Most transactions on the Deep Web accept Bitcoin system for payments allowing the purchase of any kind of products preserving the anonymity of the transaction, encouraging the development of trade in respect to any kind of illegal activities. We are facing with a with an autonomous system that advantage the exercise of criminal activities while ensuring the anonymity of transactions and the inability to track down the criminals.

But is it really all anonymous? Is it possible to be traced in the Deep Web? What is the position of the governments towards the Deep Web?
