Today we live in the cyberspace, we go to the bank, we go shopping, and make friends online, but the part of the web that we use is only 4% of the total network. In the rest, 96% aprox. there is the Deep Web and the Dark Web. In the Deep WEB there are all the databases of the government and from the enterprises, to which we do not have access, they are not indexed, we cannot go up there with Google or with Explorer. In the case of the Dark part of the Web or the Dark WEB, there are many Point to Point networks and there is also a special browser called the TOR that can explore one part of the Dark Web, the .Onion domain. The main feature of this browser is that it offers total anonymously and privacy during navigation. Since the Dark Web offers total anonymously, it is the place of preference for criminals to make their transactions online.
