“Micah’s book is a fantastic and friendly introduction for journalists, activists, and anyone else who is interested in learning to analyze large data sets but has been too intimidated by the technical details. I hope this book will inspire more people to find the stories inside the data.”—Eva Galperin, Director of Cybersecurity at the Electronic Frontier Foundation “Masterfully breaks down how to handle a data leak and provides the reader with hands-on examples to hone their skills. If only I had this book when I broke the news of the Epik data breach!”—Steven Monacelli, Special Investigative Correspondent at the Texas Observer “For more than a decade, Micah Lee has been on the cutting edge of protecting journalists and their sources from surveillance. It's a gift to all of us that he has downloaded his wisdom into this highly readable and vitally important guide.”—Julia Angwin, Investigative Journalist at The New York Times “Thanks to whistleblowing leaks, gold mines of valuable digital data now exist. There is no better account than Micah Lee’s lively and readable how-to guide for arming journalists and researchers with the tools necessary to find, excavate, and make sense of this rich data. Sourced from Lee’s experiences mining data for his hard-hitting journalistic exposes, readers will come away inspired and equipped to follow in his footsteps.”—Gabriella Coleman, Harvard Professor, Founder of Hack_Curio, and Tor Project Board Member “As a journalist who has been working with data breaches for close to ten years, actually getting to grips with that data is often the hardest part of any reporting project. Lee's clear and concise book will be an invaluable resource for reporters or researchers just dipping into this sort of data, or those looking for new techniques. I will certainly be using some of the tools myself. Hacked and dumped datasets are rich sources of information that are in the public interest, and Lee's book will only increase the number of important stories others are able to extract from them.”—Joseph Cox, Senior Staff Writer at Motherboard/Vice Media “Seamlessly blends real-world stories of whistleblowers and data dumps with a top to bottom guide on how to approach those very scenarios yourself. From protecting sources to accessing leaked data, no page is wasted. A must-read for any researcher or journalist regardless of experience.” —Mikael Thalen, Tech and Security Reporter at The Daily Dot “The world is awash in hacked and leaked data, and any investigator or journalist hoping to handle it safely and find the newsworthy threads needs to buy this book. Micah's step-by-step approach to the ethics, safety and tooling is both approachable for the average person with even basic data skills and will also be useful for those with an advanced background. A guide like this was waiting to be written.”—AJ Vicens, Reporter at CyberScoop"A comprehensive yet highly digestible resource that I would wholeheartedly recommend to anyone remotely interested by modern journalism [practices]." —Julien Voisin, Artificial Truth“Of special interest for anyone concerned with the increasing issues around cyberspace and internet database security, Hacks, Leaks, and Revelations must be considered basic, fundamental reading.”—Midwest Book Review
