Paul Sebastian Ziegler: Paul is an autodidact. You can easily tell since he sometimes messes up the pronunciation of technical terms - whitepapers in leetspeak simply don't contain phonetic spellings very often. His mind is just as chaotic with a lot of ideas, concepts and terms lying around and links between them wildly spreading like weeds. This constellation often leads to strange gasps of reality and also of computer security. And as always - "strange" is just another term for "new" and "unusual". Being a freelancer brings Paul time to write articles (hakin9) and books (O'Reilly), but pentesting and system administration take up most of his time. During free time he enjoys geeking out (e.g. turning record players into voice-controlled wireless mp3-music-stations), programming and swordplay. Also friends tend to keep him distracted a lot. Paul believes that real security can only come from broad knowledge and that security through obscurity is doomed to failure. Due to this basic assumption most of his research is dedicated to breaking security mechanisms and discovering new attack vectors to raise public awareness - - be it by analyzing wireless frames, messing with people's minds or pushing the topic of multiplatform malware.
