New York Times Editors' Choice One of The Verge 's "Top Ten Greatest Tech Books of All Time" "Greenberg is at his best when on the road -- driving through a volcano-ridden Iceland, flying a decrepit Soviet plane with nine hackers, swimming in the Black Sea with fearless Bulgarian journalists. Even seasoned observers of WikiLeaks will find something new and interesting in this book." --Evgeny Morozov, NEW YORK TIMES BOOK REVIEW "Computer hackers haven't been made into heroes like this since Stieg Larsson created Lisbeth Salander--and luckily Greenberg shares a bit of Larsson's flair for suspense, too." -- SLATE "Greenberg delves eloquently into the magicians of the all-powerful technology that shatters the confidentiality of any and all state secrets while tapping into issues of personal privacy." -- PUBLISHER'S WEEKLY "While lawmakers and law enforcers struggle with the philosophy and practicality of these issues, the people Greenberg profiles have made up their minds, and they are a few steps ahead. If you're wondering who they are and why they feel so strongly, look no further than this book." -- NEW SCIENTIST ".fascinating and well-researched.

" -- WALL STREET JOURNAL "Forbes magazine journalist Andy Greenberg takes readers on a terrific and revealing -- if considerably unsettling -- investigation into the shadowy war rooms behind our computer screens." -- CLEVELAND PLAIN DEALER "A globe trotting exploration into the heart of the contentious world of brilliant, eccentric and erratic game changers who have taken the tools at hand and turned them into powerful weapons that can -- and have in some cases -- altered the course of history.Greenberg went looking for a story and nailed it." -- PAPER MAGAZINE "A series of moving and deeply complex portraits. In all, Greenberg has created a seriously riveting read." -- CAPITAL NEW YORK "Gripping. For all the technical detail (which Greenberg excels at explaining), this book is still about human feats and failings, idealism, trust and betrayal." -- IRISH TIMES.
