[0x01] Who's Raptor?

I'm a seasoned security researcher and tech leader with 25 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 boutique company I co-founded that provides tailored offensive security services.

As a hacker and polyglot programmer of weird machines, I study how things can go wrong. I'm a core developer of the Open Source Security Testing Methodology Manual (OSSTMM), the international standard for security research, testing, and analysis. I've published articles on many computing magazines, including Phrack, 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 the open source movement.

This is my personal homepage and playground. You can send your feedback to: Marco Ivaldi <raptor[at]0xdeadbeef.info> (PGP key).
