Researchers Build a Browser-Based Darknet 163

Posted by kdawson
from the easy-come-easy-go dept.
ancientribe writes "At Black Hat USA next month, researchers will demonstrate a way to use modern browsers to more easily build darknets — underground private Internet communities where users can share content and ideas securely and anonymously. HP's Billy Hoffman and Matt Wood have created Veiled, a proof-of-concept darknet that only requires participants have an HTML 5-based browser to join. No special software or configuration is necessary, unlike with darknets such as Tor. Veiled is basically a 'zero footprint' network, in which groups can rapidly form and disappear without a trace. The researchers admit darknets are attractive to bad guys, too, but they say they think these more easily set-up and dismantled nets will be more popular for mainstream (and legit) users." In somewhat related news, reader cheesethegreat informs us that version 0.7.5 of FreeNet has hit the tubes.

      And that's exactly the reason why this will be outlawed immediately as soon as a sizable portion of the population (in the western world, folks, I'm not talking about Iran, China and Burma here) uses it to circumvent the governmental snooping that's running rampart.

      Can't outlaw it, you say? Because we're in a free world and thus they can't just simply outlaw encryption?

      Ok, they won't. What we'll get is a law that makes you liable if you "faciliate the spread of pedophilia". After all, if you help a pedo you're in the wrong as well, ain't you? Since you can't really determine what kind of data you roll around in a darknet (it would kinda defeat the purpose if you could), darknet proponents would get their IP sniffed and law enforcement would download any kind of kiddy porn they could find in the darknet. As soon as the IP of a proponent can be linked to the porn (say, a chunk came from him because it was stored at his part of the cloud), the trap closes, the law enforcement can "prove" that darknet proponents are "only" in for the kiddy porn and thus darknet is an evil tool of child exploitation.

      Gimme a single reason to believe this won't happen, I beg you.

          That would make sense. But do you think a judge will be able to tell the difference, more so when he is told that he should better NOT tell the difference? It will be made a tool that faciliates child porn, and no "honest citizen" needs it... do you think this argumentation wouldn't be used? And all too readily believed by those that don't really care too much as long as they got YouTube and Twitter?

          The idea that something should be legal because it is usually used for legal means and only in exceptions for illegal ones is one of the past. The same analogy could be used for guns, cars, almost anything human made can be used for good and ill. The problem here is that darknets are by their very definition something governments cannot regulate or control, and thus they will bring all the firepower they have into the field to destroy them if they see wide public use. The only reason we haven't seen them cracking down hard on them is simply that the amount of people using (or even knowing about) them is minimal. If darknets become a tool usable (and used) by the average computer user, they will become a target of governments which are all too eager to control and monitor what their citizens do.

              Here's your counter argument: In repressive governments like the Chinese, those darknets serve a very sensible purpose because they allow them the right to free speech and discussion of politics. Here, there is no reason for those as you may already speak your mind, and thus the only reason to use them in the "free world" is to do something illegal.

              Bet nobody realizes that they're used for exactly the same thing in "repressive" states: To do something illegal. Like, say, enjoy freedom of speech.

    Basically it seems to work sort of like a BitTorrent tracker that directs your client to other clients. So by what mechanism do you choose who to include in the "net"? If I understand correctly you sort of create channels for different purposes or groups. By using a introductory key? And how do you communicate that key? By encrypted e-mail? So any agencies that listen in on you very easily can see who you communicated with prior to your request for so and so domain holding the darknet PHP file? And how tough is that encryption? Ordinary SSL?

    It connects the user's HTML 5-based browser to a single PHP file, which downloads some JavaScript code into the browser. Pieces of the file are spread among the members of the Veiled darknet. It's not peer-to-peer, but rather a chain of "repeaters" of the PHP file, the researchers say.

      Eighty-seven point one per cent of the adult criminals in penitentiaries throughout the United States have eaten tomatoes.

      Informers reliably inform that of all known American Communists ninety-two point three percent have eaten tomatoes.

      Eighty-four per cent of all people killed in automobile accidents during the year 2004 had eaten tomatoes.

      Those who object to singling out specific groups for statistical proofs require measurements within in the total. Of those people born before the year 1850, regardless of race, color, creed or caste, and known to have eaten tomatoes, there has been one hundred per cent mortality!

      In spite of their dread addiction, a few tomato eaters born between 1850 and 1900 still manage to survive, but the clinical picture is poor-their bones are brittle, their movements feeble, their skin seamed and wrinkled, their eyesight failing, hair falling, and frequently they have lost all their teeth.

      Those born between 1900 and 1950 number somewhat more survivors, but the overt signs of the addiction's dread effects differ not in kind but only in degree of deterioration. Prognostication is not hopeful.

      Exhaustive experiment shows that when tomatoes are withheld from an addict, invariably his cravings will cause him to turn to substitutes-such as oranges, or steak and potatoes. If both tomatoes and all substitutes are persistently withheld-death invariably results within a short time!

      The skeptic of apocryphal statistics, or the stubborn nonconformist who will not accept the clearly proved conclusions of others may conduct his own experiment.

      Obtain two dozen tomatoes-they may actually be purchased within a block of some high schools, or discovered growing in a respected neighbor's back yard! - crush them to a pulp in exactly the state they would have if introduced into the stomach, pour the vile juice into a bowl, and place a goldfish therein. Within minutes the goldfish will be dead!

      Those who argue that what affects a goldfish might not apply to a human being may, at their own choice, wish to conduct a direct experiment by fully immersing a live human head* into the mixture for a full five minutes.

      * It is suggested that best results will be obtained by using an experimental subject who is thoroughly familiar with and frequently uses the logical methods demonstrated herein, such as:
