This presentation introduces the team Abracadabra and provides an overview of the surface web, deep web, and dark web. It notes that the deep web is much larger than the surface web, contains non-indexed pages, and has types of content like contextual pages and private websites. The dark web is a subset accessible only through anonymizing browsers like TOR and contains illegal activities but also freedom of speech for some. The presentation outlines how to access these networks and provides some safety tips.
