We have been reported from time to time Deep Web and we recently published to close several websites at Dark Web. It Wired, with its established Hacker Lexicon column, tries to clarify the concepts of Deep Web and Dark Web.
According to article writer Andy Greenberg, Dark Web represents 0.01% of the Web and not 90% as often reported by blogs and Media. Continuing says:
The Dark Web is not very large, it is not the 90% of the Internet, and it is not particularly secret. In fact, the Dark Web is a collection of websites that are visible to the public but they hide the IP addresses of the servers running them. This means that everyone can visit the Dark Web, but it can be very difficult to understand where they are hosted, or by whom.
The majority of Dark Web sites use Tor anonymous software, although a smaller number uses a similar tool called I2P. Both of these systems encrypt web traffic in layers and throw it into randomly selected computers around the world. Each of these servers removes one of the layers of the single encryption before passing the data to the next server. In theory, this is what prevents any spy, even those who control one of these servers sharing the encrypted data, to understand the origin of the traffic and its destination.
This way the IP addresses of the websites in question are kept hidden, but this does not mean that they are necessarily secret. Hidden services on Tor, such as the drug-selling sites Silk Road, Silk Road 2, Agora and Evolution had hundreds of thousands of regular users. Έτσι η διεύθυνση κάθε άλλο από μυστική ήταν. Όποιος τρέχει Tor και ξέρει το url ενός site, (τελειώνει σε “.onion”) μπορεί εύκολα να επισκεφθεί τις παράνομες online markets.
It should not be confused with the Deep Web
The Dark Web is not the Deep Web and does not represent 90% of the Internet. There is a confusion between the so-called Deep Web and the Dark Web.
The Deep Web is a huge collection of all its sites Internet που δεν είναι προσβάσιμα από τις μηχανές αναζήτησης. Αυτές οι unindexed ιστοσελίδες περιλαμβάνουν τεράστιους όγκους περιεχομένου, όπως forums που απαιτείται εγγραφή, δυναμικές ιστοσελίδες, υπηρεσίες σαν το Gmail και πολλά άλλα. Το πραγματικό Dark Web αντίθετα, πιθανόν αντιπροσωπεύει λιγότερο από το 0,01% του web: αναφέρει ο ερευνητής security Nik Cubrilovic who counted fewer than 10.000 hidden Tor services in a recent scan of the Dark Web. The number 10.000 is very small, compared to the hundreds of millions of regular web pages that exist on the Deep Web.

Although the Dark Web is often associated with the sale of drugs, weapons, forged documents and child pornography, all websites use the Tor service and it does not only contain "dark" websites as the name suggests. The same service is used by one of the Dark Web's first high-profile pages, Tor WikiLeaks, a hidden service created to receive leaks from anonymous sources. That idea has since been adapted into a tool called SecureDrop, software that integrates Tor's hidden services with any news organization receiving anonymous submissions. Even Facebook, as we mentioned last week, launched a websiteσελίδα on the Dark Web with the aim of better protecting (!) users visiting the website with Tor to avoid surveillance and censorship.
Of course, as is often the case, it is not known whether the Tor network can avoid surveillance by authorities and secret services. The question remains open. In early November, with coordinated action by the FBI and Europol, dozens of Tor services were confiscated, including three of the six most popular drug markets in Dark Web. Now, how exactly did the federalists discover these sites remains a mystery.
The question is: why is the Tor network not hackable? Is there anything on the web that can not be tampered with?
