Patrick spoke about telephony fraud last year at DEF CON Skytalks (“How To Make Money Fast Using A Pwned PBX”), and is a #telephreak at heart. He has over twenty years of experience, mostly with telecom manufacturers, and spent time in charge of product security for the communications security business of a fortune 100 company. When not working you can find him practicing Kung Fu, brewing beer, or picking locks with Oak City Locksport. Twitter: @unregistered436
