[0x01] Who's Raptor?

I'm a seasoned cybersecurity researcher and tech leader with 20+ years of experience, specializing in offensive security, from old school X.25 to modern mobile apps. I work as Technical Director at HN Security, a startup I co-founded that provides tailored offensive security services.

As a professional hacker and polyglot programmer of weird machines, I study how things can go wrong. As member of the ISECOM Core Team, I'm involved in the development of the Open Source Security Testing Methodology Manual (OSSTMM), the international standard for performing security testing. As a technical writer, I've published articles on many computing magazines and I've co-authored some books, such as the popular Hacking Exposed Linux. Back in the 1990s, I co-founded Linux&C (the first Italian magazine about Linux and open source), Linux Pratico, and H&C.

This is my personal homepage and playground. Take a look below for (new) stuff. Send your feedback to: Marco Ivaldi <raptor[at]0xdeadbeef.info> (PGP key).
