Key Features

  • Discusses techniques used by malicious attackers in real-world situations
  • Details unorthodox penetration testing techniques by getting inside the mind of a ninja
  • Expands upon current penetration testing methodologies including new tactics for hardware and physical attacks


Ninja Hacking offers insight on how to conduct unorthodox attacks on computing networks, using disguise, espionage, stealth, and concealment. This book blends the ancient practices of Japanese ninjas, the historical Ninjutsu techniques in particular, with the present hacking methodologies. The first two chapters incorporate the historical ninja into the modern hackers. The white-hat hackers are differentiated from the black-hat hackers. The function gaps between them are identified. The next chapters explore strategies and tactics using knowledge acquired from Sun Tzus The Art of War applied to a ninja hacking project. The use of disguise, impersonation, and infiltration in hacking is then discussed. Other chapters cover stealth, entering methods, espionage using concealment devices, covert listening devices, intelligence gathering and interrogation, surveillance, and sabotage. The book concludes by presenting ways to hide the attack locations and activities. This book will be of great value not only to penetration testers and security professionals, but also to network and system administrators.

Quotes and reviews

"The hacking community is fraught with Eastern military comparisons. Like the ninja, we are continuing to come out of the shadows of our communal origins and grow into respected members of a larger society. As our industry matures, it demands more formal education, strict regulations and an adherence to a code of ethics. Therefore it becomes increasingly difficult to incorporate the culture of the unconventional warrior into our new world. Enter Wilhelm and Andress, who make it safe to show off your fu again. By the end of this book, the security professional is given the philosophical foundation along with a practical framework from which to leverage the way of the ninja. What could be cooler?"--Overall, Ninja Hacking has excellent relevant material and a significant amount of Ninja lore and history. While this book is not a technical reference, it is an excellent choice for someone who has an interest in Ninjas or someone who is looking for inspiration to think differently about penetration testing and security concepts. The mappings for traditional Ninja skills to the skills of today are mostly well-coupled and are always relevant to how the leaders in the field are addressing security today."----Donald C. Donzal, Editor-in-Chief, The Ethical Hacker Network

"When they put "unconventional" in the title, the authors weren't exaggerating. Perhaps the most unusual book written on computer security, this volume centers around detailed descriptions of the ethics, mindset, and tactics used in the Japanese martial arts commonly called ninja. The history of ninja fighting arts and the samurai warriors who practiced them are described in the first chapter. Each subsequent chapter presents specific ninja tactics, including intelligence, use of weapons, surveillance, and sabotage, then applies them to effective computer security management. Both authors are computer security specialists. The book also benefits from a Ninjutsu consultant, Bryan R. Garner, and a technical editor, Joshua Abraham."--SciTechBookNews

"With the good blend of historical techniques and its modern day application there is something in here for everyone."--Hakin9

"Be in no doubt, credibility is high for this book..All in all, while the writing style is light, the content is, for lack of a better term, meaty. This is definitely not recommended as an entry level book, but it is an excellent resource for penetration testers and those thinking of commissioning pen tests on their systems."--Paul Baccas,, Oct. 25, 2011,
