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, in particular the historical Ninjutsu techniques, with the present hacking methodologies. It looks at the methods used by malicious attackers in real-world situations and details unorthodox penetration testing techniques by getting inside the mind of a ninja. It also expands upon current penetration testing methodologies including new tactics for hardware and physical attacks. This book is organized into 17 chapters. 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 Tzu's 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 as well as hackers.
