You may ask yourself now, “Why would anybody be interested in the Dark Web besides Criminals and Drug dealers/users?” — Well, the answer is simple. The Dark Web is not only home to criminals, but it is also a vast resource for all kinds of legitimate content; it is used by whistleblowers in countries with oppressive Governments, by journalists that report in countries that try to censor or oppress free press, and it hosts a number of sites that you would also find on the clear web, such as Facebook, BBC, and more.
OK, so why do I use the Dark Web? For me, the Dark Web is a very important resource during investigations. It is part of any OSINT (Open Source Intelligence) investigation, and life would be really hard without it for much digital forensics and OSINT investigators.
