The dark web is the World Wide Web content that exists on darknets, overlay networks which use the public Internet but which require specific software, configurations or authorization to access. The dark web forms a small part of the deep web, the part of the Web not indexed by search engines, although sometimes the term "deep web" is confusingly used to refer specifically to the dark web.

The darknets which constitute the dark web include small, friend-to-friend peer-to-peer networks, as well as large, popular networks like Freenet, I2P, and Tor, operated by public organizations and individuals. Users of the dark web refer to the regular web as the Clearnet due to its unencrypted nature. The Tor dark web may be referred to as onionland, a reference to the network's top level domain suffix .onion and the traffic anonymization technique of onion routing.

Terminology

The dark web has often been confused with the deep web, the parts of the web not searched by search engines. This confusion dates to at least 2009. Since then, especially in reporting on Silk Road, the two terms have often been conflated, despite recommendations that they be distinguished.

A December 2014 study by Gareth Owen from the University of Portsmouth found that the most commonly requested type of content on Tor was child pornography, followed by black markets, while the individual sites with the highest traffic were dedicated to botnet operations (see attached metric). Many whistleblowing sites maintain a presence as well as political discussion forums. Sites associated with Bitcoin, fraud related services and mail order services are some of the most prolific. To counter the trend of controversial content, the artist collective Cybertwee held a bake sale on an onion site.

A more recent February 2016 study from researchers at King's College London give the following break down of content by an alternative category set, highlighting the illicit use of .onion services:

Botnets

Botnets are often structured with their command and control servers based on a censorship resistant hidden service, creating a large amount of bot related traffic.

Bitcoin services

Bitcoin services such as tumblers are often available on Tor, and some offer darknet market integration. A research study undertaken by Jean-Loup Richet, a research fellow at ESSEC, and carried out with the United Nations Office on Drugs and Crime, highlighted new trends in the use of Bitcoin tumblers for money laundering purposes. A common approach was to use a digital currency exchanger service which converted Bitcoin into an online game currency (such as gold coins in World of Warcraft) that will later be converted back into money.

Darknet markets

Main article: Darknet market

Commercial darknet markets, which mediate transactions for illegal drugs and other goods, attracted significant media coverage starting with the popularity of Silk Road and its subsequent seizure by legal authorities. Other markets sell software exploits and weapons.

Hacking groups and services

Many hackers sell their services there individually or as a part of groups. Such groups include hackforum, Trojanforge, Mazafaka, dark0de and the TheRealDeal darknet market. Some have been known to track and extort apparent pedophiles.

Fraud services

Main article: Carding (fraud)

There are numerous carding forums, as well as fraud and counterfeiting services. Many such sites are scams themselves.

Hoaxes and unverified content

Main article: Hoax

There are reports of crowdfunded assassinations and hitmen for hire, however these are believed to be exclusively scams. The creator of Silk Road was arrested by Homeland Security investigations (HSI) for his site and allegedly hiring a hitman to kill six people, although the charges were later dropped.

There is an urban legend that one can find live murder on the dark web. The term "Red Room" has been coined based on the Japanese animation and urban legend of the same name. However the evidence points towards all reported instances being hoaxes.

On June 25, 2015, a creepy indie game Sad Satan was reviewed by Youtubers Obscure Horror Corner which they claimed to have found via the dark web. Various inconsistencies in the channel's reporting cast doubt on the reported version of events.

Phishing and scams

Phishing via cloned websites and other scam sites are numerous, with darknet markets often advertised with fraudulent urls.

Puzzles

Puzzles such as Cicada 3301 and successors will sometimes use hidden services in order to more anonymously provide clues, often increasing speculation as to the identity of their creators.

Illegal and ethically disputed pornography

There is regular law enforcement action against sites distributing child pornography – often via compromising the site by distributing malware to the users. Sites use complex systems of guides, forums and community regulation.

Other content includes sexualised torture and killing of animals and revenge porn.

Terrorism

There are at least some real and fraudulent websites claiming to be used by ISIL, including a fake one seized in Operation Onymous. In the wake of the November 2015 Paris attacks an actual such site was hacked by an Anonymous affiliated hacker group GhostSec and replaced with an advert for Prozac.

Commentary

Although much of the dark web is innocuous, some prosecutors and government agencies, among others, are concerned that it is a haven for criminal activity. In 2014, journalist Jamie Bartlett in his book The Dark Net used the dark net and dark web to describe a range of underground and emergent sub cultures, including social media racists, cam girls, self harm communities, darknet drug markets, cryptoanarchists and transhumanists.

Specialist news sites such as DeepDotWeb and All Things Vice provide news coverage and practical information about dark web sites and services. The Hidden Wiki and its mirrors and forks hold some of the largest directories of content at any given time.

Popular sources of dark web .onion links include Pastebin, YouTube, Twitter, Reddit and other Internet forums. Specialist companies with Darksum and Recorded Future track dark web cybercrime goings on for law enforcement purposes.

In 2015 it was announced that Interpol now offers a dedicated dark web training program featuring technical information on Tor, cybersecurity and simulated darknet market take downs.

In October 2013 the UK's National Crime Agency and GCHQ announced the formation of a 'Joint Operations Cell' to focus on cybercrime. In November 2015 this team would be tasked with tackling child exploitation on the dark web as well as other cybercrime.
