This website collects my attempts at reverse-engineering binaries – crackmes and others – in an effort to learn more about a discipline I was interested in many years ago but gradually abandoned. I use Hopper, Hex Fiend, and free Linux tools such as GDB or ltrace/strace.

Posts are listed in order of increasing complexity (kind of) as I find more difficut challenges to solve.

The tools and techniques presented here are for educational purpose only; no commercial software is reversed, attacked, or described in any way.
