Download or read book The Dark Net written by Benjamin Percy and published by HarperCollins. This book was released on 2017-08-01 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Thrilling . . . one of the best Stephen King novels not written by the master himself. . . . The setup promises furious action, and Percy delivers, like [Richard] Matheson, like King. . . An awfully impressive literary performance.”—New York Times Book Review “Masterful crafting . . . a horror story for our times.”—Minneapolis Star Tribune The Dark Net is real. An anonymous and often criminal arena that exists in the secret far reaches of the Web, some use it to manage Bitcoins, pirate movies and music, or traffic in drugs and stolen goods. And now, an ancient darkness is gathering there as well. This force is threatening to spread virally into the real world unless it can be stopped by members of a ragtag crew, including a twelve-year-old who has been fitted with a high-tech visual prosthetic to combat her blindness; a technophobic journalist; a one-time child evangelist with an arsenal in his basement; and a hacker who believes himself a soldier of the Internet. Set in present-day Portland, The Dark Net is a cracked-mirror version of the digital nightmare we already live in, a timely and wildly imaginative techno-thriller about the evil that lurks in real and virtual spaces, and the power of a united few to fight back. “This is horror literature’s bebop, bold, smart, confident in its capacity to redefine its genre from the ground up. Read this book, but take a firm grip on your hat before you start.”—Peter Straub

Download or read book Weaving the Dark Web written by Robert W. Gehl and published by MIT Press. This book was released on 2018-08-14 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exploration of the Dark Web—websites accessible only with special routing software—that examines the history of three anonymizing networks, Freenet, Tor, and I2P. The term “Dark Web” conjures up drug markets, unregulated gun sales, stolen credit cards. But, as Robert Gehl points out in Weaving the Dark Web, for each of these illegitimate uses, there are other, legitimate ones: the New York Times's anonymous whistleblowing system, for example, and the use of encryption by political dissidents. Defining the Dark Web straightforwardly as websites that can be accessed only with special routing software, and noting the frequent use of “legitimate” and its variations by users, journalists, and law enforcement to describe Dark Web practices (judging them “legit” or “sh!t”), Gehl uses the concept of legitimacy as a window into the Dark Web. He does so by examining the history of three Dark Web systems: Freenet, Tor, and I2P. Gehl presents three distinct meanings of legitimate: legitimate force, or the state's claim to a monopoly on violence; organizational propriety; and authenticity. He explores how Freenet, Tor, and I2P grappled with these different meanings, and then discusses each form of legitimacy in detail by examining Dark Web markets, search engines, and social networking sites. Finally, taking a broader view of the Dark Web, Gehl argues for the value of anonymous political speech in a time of ubiquitous surveillance. If we shut down the Dark Web, he argues, we lose a valuable channel for dissent.
