[0x01] Who's Raptor?

I'm a seasoned information security researcher and consultant, specializing in networking (from old school X.25 to modern Wi-Fi), telephony (POTS, mobile, VoIP), and cyber-physical systems (SCADA and process control technologies in general). I work as Team Manager and Principal Security Advisor at @Mediaservice.net (Cybaze), a leading security advisory firm based in Italy, where I'm in charge of project and team management, penetration testing, compliance audits, vulnerability research, and exploit development. Basically, I'm a professional hacker and project manager. I hold the following certifications: 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. I'm also contributing to the Hacker Highscool (HHS), another ISECOM project promoting security awareness for teens. 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 90s, I co-founded Linux&C (the first Italian magazine about Linux and open source), Linux Pratico, and H&C.

I'm a polyglot programmer and this section is dedicated to some of the programs and scripts I've written. Most of this stuff is experimental, standard disclaimer applies.
