Cyberjutsu is a practical cybersecurity field guide based on the techniques, tactics, and procedures of the ancient ninja. Cyber warfare specialist Ben McCarty’s analysis of declassified Japanese scrolls will show how you can apply ninja methods to combat today’s security challenges like information warfare, deceptive infiltration, espionage, and zero-day attacks.

Learn how to use key ninja techniques to find gaps in a target’s defense, strike where the enemy is negligent, master the art of invisibility, and more. McCarty outlines specific, in-depth security mitigations such as fending off social engineering attacks by being present with “the correct mind,” mapping your network like an adversary to prevent breaches, and leveraging ninja-like traps to protect your systems.

You'll also learn how to:

  • Use threat modeling to reveal network vulnerabilities
  • Identify insider threats in your organization
  • Deploy countermeasures like network sensors, time-based controls, air gaps, and authentication protocols
  • Guard against malware command and-control servers
  • Detect attackers, prevent supply-chain attacks, and counter zero-day exploits

Cyberjutsu is the playbook that every modern cybersecurity professional needs to channel their inner ninja. Turn to the old ways to combat the latest cyber threats and stay one step ahead of your adversaries.

"As novel as it is illuminating, as it looks deep into the past. . . . [McCarty] provides a remarkably comprehensive tour of his subject, which is especially impressive for such a concise work that’s well under 300 pages. In it, he covers such as topics as mapping networks and authentication, and provides unconventional tips, as well . . . A thoughtful, original, and thorough guide to cybersecurity."
Kirkus Reviews

"Pairs modern information security methods with ancient Japanese traditions, elevating both subjects in order to elucidate elements of the former. . . . an easy resource whose reference material flows well."
Foreword Reviews

"A good quality book."
—Antony Cummins, The Historical Ninjutsu Research Team

"This helpful manual explores the field of cybersecurity, providing tips, tricks, and proven methods to help companies keep online information out of the hands of hackers. . . . Combining philosophical exercises with more concrete plans of action, McCarty blends new and old, complex and simple, to craft this intricate guide."

As such, the book is likely to prove an invaluable resource for individuals and organizations looking to improve their cybersecurity practices."
—Erin Britton, San Francisco Book Review

"A very well researched and clearly organized book that uses Japanese history quite cleverly to illustrate modern cybersecurity problems, suggesting ways to counter technological invaders and hackers based on techniques used to defend castles against attacks by clever and resourceful ninja."
—Catherine Langrehr, Indie Reader, Starred Review

"The exercises are of a kind that would deeply kindle readers’ interest and spur them on to intense problem-solving activity as well as hands-on experimentation in a naturally appealing manner, particularly if you grew up loving adventure/mystery stories involving castles, kings, and queens. . . . [geeks will] find it highly enjoyable and challenging!"
—Raju Chacko, Reedsy

"May appeal to CEOs in the same way they might turn to Sun Tzu’s The Art of War to level up their plan of attack. The book is also a good overview of cybersecurity for students and anyone considering a career in this expanding field. . . . Cyberjutsu, with its knowledge of the past and its applications for the future, is sure to inspire both cybersecurity insiders and the curious."
—Joanna Poncavage, BookTrib

"A labor of love . . . There is much value in the descriptions, analogies and schemes as described. The cyber technology presented is correct and complete. I am no expert in Ninja warfare, but the analogies absolutely makes sense."
A Book Junkie Reviews

"I had a lot of fun reading this book. It is by far one of the easiest technical books that I have read in a while. I’m not sure whether that was due to the comparisons to Shinobi holding my interest. Or whether it was due to the authors writing style that made it easy to read. Either way I blitzed through this book quickly and have recommended it to a few of my colleagues in the Cybersecurity industry.""
—HaXeZ, Medium

"Don’t let its whimsical title fool you; this book is a practical and prescient compendium of cybersecurity concepts that lends itself to anyone considering a career in this expanding field along with organizational leaders seeking to level up their plan of attack with ninja-fueled tactics, techniques and procedures."
—Herald & Review
