"A compelling history of cyberwarfare."

– Evan Osnos, The New Yorker

“A consistently eye-opening history of our government’s efforts to effectively manage our national security in the face of the largely open global communications network established by the World Wide Web. . . . The great strengths of Dark Territory . . . are the depth of its reporting and the breadth of its ambition. . . . The result is not just a page-turner but consistently surprising. . . . One of the most important themes that emerges from Mr. Kaplan’s nuanced narrative is the extent to which defense and offense are very much two sides of the same coin. . . . The biggest surprise of Dark Territory is the identity of the most prominent domestic heroes and villains in the “secret history.” . . . Dark Territory is the rare tome that leaves the reader feeling generally good about their civilian and military leadership.”

– The New York Times

“A book that grips, informs and alarms, finely researched and lucidly related.”

– John le Carré

“Comprehensively reported history . . . The book’s central question is how should we think about war, retaliation, and defense when our technologically advanced reliance on computers is also our greatest vulnerability?”

– The New Yorker

“Dark Territory captures the troubling but engrossing narrative of America’s struggle to both exploit the opportunities and defend against the risks of a new era of global cyber-insecurity. Assiduously and industriously reported. . . . Kaplan recapitulates one hack after another, building a portrait of bewildering systemic insecurity in the cyber domain. . . . One of the deep insights of Dark Territory is the historical understanding by both theorists and practitioners that cybersecurity is a dynamic game of offense and defense, each function oscillating in perpetual competition.”

– The Washington Post

Dark Territory offers thrilling insights into high-level politics, eccentric computer hackers and information warfare. In 15 chapters—some of them named after classified codenames and official (and unofficial) hacking exercises—Kaplan has encapsulated the past, present and future of cyber war.

– The Financial Express

“An important, disturbing, and gripping history arguing convincingly that, as of 2015, no defense exists against a resourceful cyberattack.”

– Kirkus Reviews, starred review

“Kaplan dives into a topic which could end up being just as transformational to national security affairs as the nuclear age was. The book opens fast and builds from there, providing insights from research that even professionals directly involved in cyber operations will not have gleaned. . . . You will love this book.”

– Bob Gourley, CTOvision.com

“The best available history of the U.S. government’s secret use of both cyber spying, and efforts to use its computer prowess for more aggressive attacks. . . . Contains a number of fascinating, little-known stories about the National Security Agency and other secret units of the U.S. military and intelligence community. . . . An especially valuable addition to the debate.”

– John Sipher, Lawfare

“Fascinating . . . To understand how deeply we have drifted into legally and politically uncharted waters, read Kaplan’s new book, Dark Territory: The Secret History of Cyber War.”

– George F. Will, The Washington Post

"Fred Kaplan’s Dark Territory may become a classic reference for scholars and students seeking to understand the complicated people who ushered the United States into the cyber-conflict era and the tough decisions they made."

– Rear Admiral Grace Hopper, Director, Center for Cyber Conflict, US Naval War College, Proceedings of the U.S. Naval Institute

“Deeply sourced. Luckily, he’s not slavishly loyal to his sources.”

– Pittsburgh Post-Gazette

A “Hot Type” Book Pick for March 2016

– Vanity Fair

A “Hot Tech Book of 2016”

– Tech Republic

“Worthy of any spy thriller. . . a strong narrative flow . . . impressivelydetailed . . . deeplyrelevant . . . vital.”

– The National (UAE)

“Jarring . . . a rich, behind-the-headlines history of our government’s efforts to make policy for the jaw-dropping vulnerabilities of our ever-increasing dependence on computers. . . . Kaplan renders a vivid account of the long struggle waged by presidents, bureaucrats, generals, private-sector CEOs, and privacy advocates . . . Kaplan enjoys considerable credibility in defense circles, but he guides us through the dark territory of cyber conflict with an omniscient-narrator voice reminiscent of Bob Woodward’s behind-the-scenes books. . . . Today, Kaplan argues, it is precisely U.S. pre-eminence in the network connectivity that makes us the most vulnerable target in the world to cyber sabotage.”

– Washington Independent Review of Books

“Pulitzer-prizewinning journalist Fred Kaplan’s taut, urgent history traces the dual trajectory of digital surveillance and intervention, and high-level US policy from the 1980s on.”

– NATURE

“Dark Territory is a remarkable piece of reporting. Fred Kaplan has illuminated not merely the profound vulnerabilities of our nation to cyber warfare, but why it has taken so long for our policy-makers to translate indifference into concern and concern into action. This is a vitally important book by a meticulous journalist.”

– Ted Koppel, author of Lights Out: A Cyberattack, A Nation Unprepared, Surviving the Aftermath

“A fascinating account of the people and organizations leading the way towards a cyber war future.”

– Dorothy E. Denning, author of Information Warfare and Security, 1st Inductee, National Cyber Security Hall of Fame

“A very in-depth work... its content is enlightening and intelligent and the secrets it uncovers are astounding.”

– The News Hub

“Everyone has heard the term 'cyber warfare.' Very few people could explain exactly what it means and why it matters. Dark Territory solves that problem with an account that is both fascinating and authoritative. Fred Kaplan has put the people, the technologies, the dramatic turning points, and the strategic and economic stakes together in a way no author has done before.”

– James Fallows, national correspondent, The Atlantic

– The Times Literary Supplement

"It’s not easy to write an engaging book on cyberwar, and Kaplan, a national security columnist at Slate, has done an admirable job. He presents a clear account of the United States’ evolution into a formidable cyberpower, guiding the reader through a thicket of technical details and government acronyms."
