Pornography sites are most popular among the hidden services, websites that are only through the Tor network to visit. That says researcher Gareth Owen, who Tor relays turned to look at registering hidden services.

Researcher Owen, who revealed his findings did at the CCC security conference in Hamburg, studied for six months the Tor network with forty Tor relays and mat so include any hidden services were the most popular. Child pornography sites were found popularity with head and shoulders above to stabbing from other sites. The number of child pornography sites is not too bad: there are relatively few hidden services that offer child pornography, but who are, therefore, the most popular.

In practice, host all websites as “abuse” were classified child pornography.

Tor is a combination of software and a network of routers that can be used to relatively anonymous surfing on the Internet, including censorship can be circumvented. The traffic is routed through multiple nodes; the first node knows who the user is only aware of the content of the traffic, while the last node only the content of the traffic and not the identity of the user knows. Tor is full for The Onion Router: the traffic is as it were peeled off.

Tor can be used to ‘normal’ websites to visit, which will also be accessible by default, but also to achieve special Tor sites that can be visited through Tor. These sites are called hidden services, although the term “dark nets” or “the deep web ‘is also popular among governments. As visitors to Tor hidden services are anonymous. It was those hidden services that Owen, who is linked to the University of Portsmouth, took a closer look.

With the Tor nodes that turned Owen, he could measure how often the unique address of a hidden service was requested. With a crawler was vervoglens brought the contents of the root of the domain, so that the sites could be classified. Owen has thereby incidentally, not all hidden services can count and index, but only the hidden services that were visited by its nodes.

“We were surprised by the results,” said Owen. Sites that were classified as “abuse” – in all cases websites offering child pornography – proved the most popular. It is difficult to say exactly how popular they are: Owen only managed to measure the number of hidden service directory requests. A HsdR hangs between a unique visitor and visit, and again after re-connecting to the Tor network. Eighty percent of the HsdR’s turns out to go to a child pornography site. It is impossible to say whether a HsdR is done by a man; the number of requests can also be boosted by bots and spiders, for example, to index the sites.

According to Owen would managers Tor relays may decide to no longer process requests to child pornography sites, or the operators of the Tor network could block the sites. “I’m not saying that to happen, I’m just saying that it is technically possible,” emphasizes the researcher. “Whether that should be done, the Tor project must decide.”

The study also shows that websites related to drugs are the most popular, followed by market places and sites as “fraud” are stamped. The software is often used for command-and-control servers for botnets, something that has long been known. Many hidden services appear, moreover, only a short time to be in the air, and after one or a few days, again disappeared.

The Tor Project has previously indicated that the project abuse of the Tor software seriously, but that the project would block any websites or want to install backdoors. “It is dangerous for policymakers assume that blocking and filtering is a good solution,” says the project. According to Tor is better to actually solve the problem than to hide it. Moreover, emphasizes the project, technology will always be abused by criminals.

Earlier on Tuesday said Jacob Appelbaum, the foreman of the Tor Project, investigative services regularly put pressure on the project to build in backdoors. He called on his audience therefore to include publicly for the Tor. “The pressure is very heavy, and we can not do it alone,” says Appelbaum.

Update, 22:52: Roger Dingledine, the main developer of Tor, writes in a comment that traffic to hidden services represents only 1.5 percent of the Tor traffic. The Tor project comes later with more information.
