What is the Shadow Web?

The terms "shadow web" and "abyssal web" are not widely recognized or agreed upon within the field of internet technology. They appear to be popular within the realm of urban legends, myths, and folklore related to the internet. They are often used interchangeably with "Darknet" or "Deep web", but they are not officially recognized terms. The "Deep web" refers to all parts of the internet that can't be accessed through a simple search via traditional search engines like Google, Yahoo, or Bing. These pages can include personal email accounts, online banking accounts, membership-only websites or protected pages within a website, restricted access scholarly databases, etc. The "Darknet" or "Dark Web", on the other hand, is a portion of the Deep web that has been intentionally hidden and is inaccessible through standard web browsers. It's accessed via special software like Tor (The Onion Router) or I2P (Invisible Internet Project). Here, websites exist with ".onion" domains and are not indexed by search engines. The sort of activities that happen on the Darknet vary; while there's a large amount of illegal activity, like illegal trade, communication between whistleblowers and journalists as well as other legal, privacy-focused activities can also take place. As for the other terms you mentioned - "shadow web" and "abyssal web", there is no concrete evidence to prove the existence of these networks. They are often described as layers that go even deeper than the Dark Web, but most often, these descriptors are linked to internet hoaxes. It's important to approach such topics with skepticism and prioritize online safety. When in doubt, it's always best not to access unknown parts of the internet without sufficient knowledge of internet security protocols.
