Publicly accessible sites for information, education, entertainment, commerce and more. As much as 50% of the web comprises controlled access sites like those belonging to governments, research and proprietary information – collectively called the deep web.
The balance, a substantial section of the web, is called the dark web – a labyrinth of underground sites, commerce and trade that deal in stuff which will boggle any one’s mind. Sites come up temporarily, business is transacted with bitcoins (or equivalent) and disappear – all in complete anonymity powered via specialized browsers and tools.
This is where corporate secrets are sold, where stolen (or leaked) credit card, credentials and code are found and traded.
