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.

Professionally I have been working as an incident responder and later as a penetration tester for a major US financial institution.

I am currently on a year-long research sabbatical (August, 2013 to August, 2014) studying reverse engineering, malware analysis, vulnerability research, and exploit development.

Other than security research, I enjoy Krav Maga system and urban exploration photography. I am also a native Russian speaker.
