Cyberjutsu vs The Perfect Weapon: Which Should You Read?
Two cybersecurity books on Strategy, compared honestly: who each is for, what each does best, and which to read first.
Ben McCarty maps declassified medieval ninja scrolls onto modern adversary tradecraft. More analogy-driven than technical, useful for security-program framing.
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.

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.
