15 escalating labs take you from your first password check to packed binaries, Android APKs, and live Frida hooks. No 400-page theory prelude — you patch real code in Chapter 4, and it never slows down.
Every chapter ends with a lab binary written for this book — legal to reverse, built to teach one precise idea. You get the binary, the source, and a fully annotated walkthrough of the solution.
Find the string compare in Ghidra, flip one jump in x64dbg, make the patch permanent.
From "it says wrong serial" to understanding the math — without ever seeing the source.
IsDebuggerPresent, timing checks, and a sneaky one — then bypass each without crashing.
Dump from memory, rebuild the import table, no automatic unpacker allowed.
A custom-encoded blob in the binary. Static decode + runtime interception, both ways.
From APK to hooked method call at runtime — on a device or emulator, your pick.
Four parts, fifteen chapters. Each part ends with a "boss lab" that combines everything before it.
Everything used in this book is free and industry-standard — the same tools people use on the job. NSO this is not, but Ghidra, x64dbg and Frida are what professionals actually open first.
One-time payment, no subscription. Lifetime updates — this book improves and you never pay again.
First Blood: Finding the Password Check is the whole book in miniature: recon, Ghidra, one clean patch in x64dbg, and a permanent fix. If you like how it teaches, you'll like the other fourteen.
