Siva Kumar and Anderson are uniquely qualified to identify these challenges given their decades of experience and research on the topic. Further, their writing is both accessible and enjoyable despite going into deep technical details. As AI/ML systems increasingly pervade everyday life, the lessons they impart are critical for everyone from casual technology users to corporate leaders to policy makers." ―Frank Nagle, Asst. Professor of Business Administration, Harvard University

"A reality of the digital age is that every innovation contains security risk, and every security risk attracts an attacker. Ram Shankar Siva Kumar and Hyrum Anderson fire a much-needed warning flare in NOT WITH A BUG, BUT WITH A STICKER: we over-trust artificial intelligence at our peril. Every leader and policymaker should read this compelling and persuasive book." ―Nate Fick, New York Times bestselling author, and former CEO of the cybersecurity firm Endgame

"The intersection of technology and national security has always been a story of tension between attack and defense. With AI, the speed of attack has accelerated dramatically, while defense has not kept pace. This excellent, lively analysis shows how AI's limitations and vulnerabilities can jeopardize national security. Most importantly, Siva Kumar and Anderson provide concrete, feasible recommendations for taking steps today to bolster defenses against the certainty of pervasive adversarial AI attacks." ―Lt. Gen. John (Jack) N.T. Shanahan, USAF (Ret.); inaugural Director, U.S. Department of Defense Joint AI Center (JAIC)

"This is such a timely and readable book―the authors do a fantastic job of explaining complex topics and modern research in plain language with plenty of references for further exploration. AI and ML have immense utility and potential, and it's critical for security teams, builders, and operators to understand the sharp edges and pitfalls along with the benefits." ―Jason Chan, Former Information Security Leader, Netflix

"NOT WITH A BUG, BUT WITH A STICKER is an informative, engaging, and fun foray into how AI can be easily fooled. An excellent read for both technical and nontechnical readers, the book provides a global perspective on what's happening today and empowers the reader with tools to make informed decisions that impact tomorrow. This book focuses on both technical and human interventions to ensure the secure use of AI systems." ―Dr. Rumman Chowdhury, Founder, Bias Buccaneers

"Siva Kumar and Anderson skillfully deliver a message that AI practitioners, decision-makers, and users of AI systems must hear: our AI systems are not safe, and the blind trust placed into AI is putting our nation at risk. With ample background, anecdotes, and data, the authors make the science accessible, update the current academic discourse, and highlight the implications for public policy. No matter whether you work in the field or are an AI enthusiast, this book is a must-read." ―Sven Krasser, Senior Vice President and Chief Scientist, Crowdstrike

"As AI systems get more capable and are deployed in a wider range of contexts, more and more people will try to break them, with wide-ranging consequences. Not with a Bug, but with a Sticker provides a timely overview of this emerging risk landscape and what can be done about it." ―Miles Brundage, Head of Policy Research, OpenAI

"As AI becomes infused into all computer systems, from social networks to business-critical infrastructure and defense systems, the security of those systems depends on the security of the AI they use. This book presents the unique risks and considerations of AI with engaging stories and insightful examples. It is a wake-up call to security professionals and organizations adopting and developing AI." ―Mark Russinovich, Azure CTO and Technical Fellow, Microsoft

"'The threat is not hypothetical'―a quote used by the authors to open the book remains top of mind as you come to the conclusion of this brilliant work. In the final paragraphs, one thing is clear: there is a call to action, and we must act 'hand in hand' on securing AI systems with haste." ―Vijay Bolina, Chief Information Security Officer, DeepMind

"Siva Kumar and Anderson take you on a wild ride uncovering the victories and triumphs of AI/ML. This should be required reading to become AI/ML literate in the field." ―David Brumley, Professor of ECE and CS, Carnegie Mellon University

"Trust, in ways both good and bad, is emerging as a critical aspect of the relationships we are coming to have with AI. NOT WITH A BUG, BUT WITH A STICKER is an eye-opening book that will change the way you think about the systems that pervade our world―and its lessons should be taken to heart by all who build them." ―Brian Christian, author of The Alignment Problem

"NOT WITH A BUG, BUT WITH A STICKER is a rare inside look at the absurd AI quirks that are keeping security experts awake at night. I'm going to start bringing up examples from this book immediately." ―Janelle Shane, author of You Look Like A Thing And I Love You: How AI Works And Why It's Making The World A Weirder Place

"At last―and not a moment too soon―a book that in plain language describes the distinct and deep issues of securing now-ubiquitous machine learning tools. Whether you're looking to deploy them in your own domain, or simply among the billions of people now subject to them, this is a vital read." ―Jonathan Zittrain, George Bemis Professor of International Law and Professor of Computer Science, Harvard University

"We are fast entering a world of powerful but brittle AI systems, one where failures can result in catastrophic consequences. Siva Kumar and Anderson have written an essential guide for understanding the unique ―and troubling ―failure modes of AI systems today. Through easily accessible examples and anecdotes, they break down the problems of machine learning systems and how society can address them to build a safer world." ―Paul Scharre, author of Four Battlegrounds and Army of None

"Siva Kumar and Anderson are veterans at the intersection of machine learning and security, and in this work, they delight us with a guided tour across the history of this fascinating field.
