Peter Kacherginsky (iphelix) is the author of The Sprawl project and all of its original content. I live in San Francisco, CA. You can usually find me at local hacker/security meetings and con fere nces.

Most of my free time goes to security research and development. Over the years I had great times hanging out with smart and unique individuals as well as messing with wireless, search engines, traffic analysis, tor, password cracking and other fun subjects. Currently, I am slowly losing sanity studying reverse engineering, malware analysis, and exploit development ;-)

Other than security research, I enjoy Krav Maga system and urban exploration photography.
