About the Book

Spies, Lies and Cybercrime

The Threat:
If we don’t do anything to understand and curb the effects of the Dark Web, then we might as well pledge allegiance to its nefariousness.  
The Solution:

Spies, Lies and Cybercrime will appeal to every person curious or frightened by the prospect of a cyberattack, from students and retirees to the C-Suite and boardroom. My readers will take up arms in the current cyber war instead of fleeing while the village burns. They will become email archeologists and threat hunters, questioning every movement online and spotting the attackers hiding in every shadow. They will learn how to embed cybersecurity intrinsically into the culture and technology of their businesses and lives. Only then can we begin to move the needle toward a world safe from cyber-attacks.

Praise for Spies, Lies, and Cybercrime

Cybercriminals are the wrong kind of disruptors. One breach can sink a business—or a billion-dollar idea. Spies, Lies and Cybercrime is essential reading for anyone who wants to build boldly and stay protected.
Marc Randolph
Co-Founder and First CEO of Netflix
Part spy story, part survival manual - O’Neill has written the ultimate guide to outsmarting the predators who prowl our digital world. Spies, Lies, and Cybercrime is a chilling and essential wake-up call that reads like a thriller, but every word is terrifyingly real.
Brad Thor
#1 New York Times bestselling author of Edge of Honor
Required reading for founders and innovators. O'Neill helped catch the most famous spy in US history and now hunts cybercriminals. He brings both worlds to life brilliantly in Spies, Lies, and Cybersecurity, which reads like a thriller but delivers like a playbook. Read it for the same reason I did: you don't want to become a case example for his next book.
O’Neill deftly takes his decades of experience as a spy catcher and turns his attention to cybercrime. The result is an astonishingly up-to-date review of the tools and techniques used by criminal hackers around the world to deceive and defraud you. O’Neill will have you on the edge of your seat as he helps you get a leg-up on protecting yourself, your family, and your company.
O'Neill starts strong and never lets up, gripping readers with rich accounts of the myriad ways cybercriminals attack us and offering practical ways to beat them at their own game. This is an essential -- and relentlessly fun -- read for anyone interested in espionage, counterintelligence, or cyber issues.
Dr. David Priess
Former CIA officer and author, The President's Book of Secrets
This book is an absolute requirement for all of us to read as leaders and private citizens. Highly accessible even to a novice in the realm of cyber space, it helps expose and then equip us against the myriad dangers of the dark web. Spies, Lies and Cybercrime is Illuminating, disturbing and important. Don’t miss this. .

Eric O’Neill pulls back the curtain on the modern battlefield we can’t see but live in every day. Spies, Lies, and Cybercrime is, in part a gripping story and in part, a survival manual. This is a must-read that will open your eyes and will change how you think about trust, technology, and the threats we face.
Jenn Donahue
Author of Becoming The Warrior, award-winning Engineer, Keynote Speaker, US Navy Captain (ret), Entrepreneur
This book opened my eyes to the cyber enemy that hunts us, and it scared the hell out of me. As the saying goes in Naval Aviation: Sometimes it's better to be lucky than good. It's time to stop being lucky in your cyber defense. Eric O'Neill will teach you how to be good.
CAPT J.J. "Yank" Cummings USN (Retired)
Third Commanding Officer of the USS Gerald R Ford First Technical Advisor for TOPGUN Maverick
As someone who spent a decade undercover for the KGB, I recognize the tactics of deception—whether they come from a Cold War operative or a keyboard warrior ensconced in his mother's basement. In Spies, Lies and Cybercrime, Eric O’Neill makes one thing clear: today’s most dangerous cyberattacks are espionage by another name. It takes a spy hunter to stop a spy, and Eric is one of the best. Read this book and follow his advice to avoid ending up a helpless victim.
Jack Barsky
Former KGB deep-cover operative and author of Deep Undercover
