Our data show that in net terms, only a small fraction of Tor users employ the anonymity system for likely malicious purposes. In the case of the Tor anonymity network, our data provide clear, if probabilistic, answers to these questions. Others emphasize its socially beneficial potential as a privacy-enhancing tool and censorship circumvention technology ( 17– 22). With these diverse supply-side and demand-side functions ( 6), many point to the socially harmful uses of Tor as an anonymous platform for child abuse imagery sites ( 7, 8), illicit drug markets ( 9– 13), gun sales ( 14, 15), and potential extremist content that has shifted to the Dark Web after extensive Clear Web content moderation efforts ( 16). They can also use the Tor browser to anonymously read either these Onion/Hidden Services (i.e., sites with rendezvous points located internal to the Tor network) or to access Clear Web sites ( 1– 5). Tor users can act as publishers of content by using the network to anonymously administer Onion/Hidden Services for the use of others. * Although other similar tools exist, The Onion Router (Tor) is currently the largest anonymity network. While the dark web masks a user's identity, location and any traces of persona, Holt's findings reveal the need for further investigations, and potential growth and impact.Debate rages about the social utility of an anonymous portion of the global Internet accessible via the Tor network and colloquially known as the Dark Web ( 1). Common threads between the sellers included: vendors deliberately selling hand and long guns the use of bitcoin for payment sellers' shops requesting PO Boxes to ship the product and how sellers delivered the guns. Holt and partners dug into shops, or single-owner websites hosted on Tor-a dark web browser, using a scaping tool to track vendors anonymously selling firearms as well as to identity patterns of their operations. Regardless, Holt said that because the dark web allows for total anonymity, it supports his theory that the dark web buyers are those who wouldn't be able to purchase a firearm legally. One example would be a buyer who can't legally obtain a firearm another explanation would be that the buyer lives in a country with stricter gun laws. There are many reasons buyers could turn to the dark web to purchase a weapon, Holt explained in a press statement. "We know so little about the distribution of firearms sold on the dark web that it's kind of a black hole, similar to illicit pharmaceuticals and narcotics: We know people buy them online, but we don't know to what extent," said Holt.
