Dark web

The Dark web is a web content that exists on darknets (overlay networks) that use the Internet but require specific software, configurations, or authorization to access. It is a hidden portion of the internet as a form of a small part of the deep web that can't be found using generic search engines or requires certain browser modifications and plug-ins to view, such as the Tor browser. Other software and general browsers and their respective modifications exist as well.https://www.npr.org/sections/alltechconsidered/2014/05/25/315821415/going-dark-the-internet-behind-the-internet
== Overview ==
The dark web requires certain plug-ins, permissions, modifications or any other forms of extra ability that would allow them to view generally hidden content.https://www.npr.org/sections/alltechconsidered/2014/05/25/315821415/going-dark-the-internet-behind-the-internet Because of this, a large majority of the internet falls under the category of "deep web", and it is estimated that around 90% (96%-99%) of the internet is part of the deep web.https://www.csoonline.com/article/3249765/what-is-the-dark-web-how-to-access-it-and-what-youll-find.html#:~:text=Estimates%20place%20the%20size%20of,as%20the%20%E2%80%9Cclear%20web%E2%80%9D.
Dark web sites commonly host illicit content such as child pornography and black markets. The most popular top-level domain name dark web sites use is the .onion domain.
Some of if not most of the websites visited by the average person may count as the "dark web", such as personal information (ex: bank account information) and hidden pages (ex: website accounts). Any web-page or POV on a page that needs extra authentication or permissions to view will fall under the category of "deep web".
== Categories ==
The dark web or dark net is a category of the deep web that hosts malicious, often disturbing, and generally illicit content. It is estimated that the dark web is around 400-550 times larger than the surface webhttps://www.britannica.com/story/whats-the-difference-between-the-deep-web-and-the-dark-web#:~:text=The%20Dark%20Web%20is%20only,%2Dto%2Daccess%20Deep%20Web.
=== Markets ===
Darknet markets refer to mostly commercial websites that exist to sell illegal items, such as illicit drugs, illicit pornography, weapons and arms, among other such things. Most of them will only accept bitcoin as paymenthttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC7608591, due to its level of privacy.
=== Hacking & Malware ===
Hacking groups/services and malware (most commonly adware and ransomware) are very present on the dark web, and are defined as any number of people/bots that have the ability to break into another's private data and manipulate it using a client-sided ability.
=== Illicit pornography ===
Illegal pornography, more specifically, child pornography, is one of the most popular services and forms of content in the dark web. It is estimated around 80% of the traffic within the dark web is towards sites or files containing child pornography, despite it being difficult to find at firsthttps://doi.org/10.1007%2Fs11277-020-07143-2. 
=== Gore & violence ===
While gore and graphic imagery is not illegal in most countries, it is very easy to find on the dark web. Beheadings, dismemberment, snuff films, torture, and other forms of violent media make up the majority of said content.
=== Illicit drugs ===
Drug marketplaces that sell illegal drugs make up a majority of the darknet markets, along with guns and other such violent weapons.
=== Weapons & arms ===
Guns, bombs, and other such weapons are a large part of many darknet markets, along with drugs and pornography. Most of these are often taken advantage of by criminals and terroristshttps://doi.org/10.1080%2F1057610X.2015.1119546.
=== Terrorism ===
Terrorist markets, forums, or any other content that could further acts of terrorism are also in the dark web, and often take form of internet forums and social medias that are used by terrorists to create plans with each other.
