powerful weapon we wield in the fight against cybercriminals and illicit nation states who mistakenly believed that the blockchain and cryptocurrency offered them cover. Greenberg tells the tale of this new weapon with his usual eye for technical accuracy and gift for storytelling. This is how the good guys win."
Nicole Perlroth, New York Times bestselling author of This Is How They Tell Me the World Ends

A gripping, stranger-than-fiction tale of how a small team of geeks and federal agents cracked what was once thought to be untraceable cryptocurrency. Page after page, Tracers in the Dark proves beyond a reasonable doubt that there is no better reporter covering the wild west of the internet than Andy Greenberg.
Garrett M. Graff, New York Times bestselling author of The Only Plane in the Sky and Watergate

A riveting non-fiction thriller from an exceptional reporter and storyteller. Tracers in the Dark shines a light on how cryptocurrency has been used to hide human rights abuses and trafficking by global crime syndicates and how a team of crypto tracers learned to expose those schemes by finding a new way to follow the money.

Library Journal (starred review)

"Greenberg examines in fascinating detail how criminals have employed technology for their nefarious ends...He brings to vivid life the assorted players, including the agents who cracked the crimes, those in law enforcement who succumbed to the allure of fast money on the dark web, and the private citizens who ushered in the golden age of cryptocurrency tracing. This is a must-have for the true crime shelf."
Publishers Weekly (starred review)

Spellbinding.... Written with great enthusiasm and with an ear for the dramatic turn of phrase...this is the kind of book that yanks the reader s eyes wide open.... Lively, highly relevant, and more than a little scary.
Booklist

"A sinuous, eminently readable story of the darker corners of cyberspace...  Reminiscent in all the best ways of Clifford Stoll s Cuckoo s Egg, smoothly blending crime writing with matters of the deepest techno-geekery. An absorbing work of true crime.
