[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 performing security testing. 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).
