Cyberjutsu

Cybersecurity for the Modern Ninja

Ben McCarty

Ben McCarty maps declassified medieval ninja scrolls onto modern adversary tradecraft. More analogy-driven than technical, useful for security-program framing.

The Perfect Weapon

War, Sabotage, and Fear in the Cyber Age

David E. Sanger

The NYT national security correspondent's account of how cyber weapons became the tool states reach for short of war, from Stuxnet to Russian election interference. Strong on the politics and decision-making, light on the technology.

Read this if

Security program managers and CISOs looking for non-technical framing for executive conversations. McCarty's analogies between feudal-Japan ninja tradecraft and modern adversary behaviour are unusual but practical for anchoring strategic discussions.
Readers who want the statecraft view of cyber, how it is debated in situation rooms and weighed against diplomacy. Pairs well with Sandworm and This Is How They Tell Me the World Ends.

Skip this if

Practitioners wanting technical depth or hands-on guidance. The book is metaphor-driven and conceptual; engineers and analysts will find the depth thin.
Skip this if you want technical depth or fresh reporting; it is a strategic synthesis, and a US-centric one, that practitioners will already know in outline.

Key takeaways

  • The ninja-vs-modern-adversary analogies hold up surprisingly well, particularly around deception, patience, and information operations.
  • The framing is most useful when explaining adversary thinking to non-technical executives; the chapters on deception and counter-intelligence are the strongest.
  • Treat the book as strategy-and-vocabulary scaffolding, not as technical training; its value is in framing decisions, not making them.
  • Cyber weapons are attractive precisely because they sit below the threshold of armed conflict, which makes deterrence and norms genuinely hard.
  • The same offensive capabilities the US built and lost (the NSA leaks) came back as the raw material for global attacks.
  • Decisions about cyber operations are political and improvised, not the product of settled doctrine.

How they compare

We rate The Perfect Weapon higher (4/5 against 3/5 for Cyberjutsu). For most readers, that means The Perfect Weapon is the primary pick and Cyberjutsu is a useful follow-up.

Both books target beginner-level readers, so the choice is about topic, not difficulty.

Cyberjutsu and The Perfect Weapon both cover Strategy, Narrative, so reading them in sequence reinforces the same material from different angles.
