I'm a world-wide security evangelist, meaning I write and speak about hackers, cryptography, fraud, malware and all that interesting stuff.

I've spoken at over 30 conferences on all six developed continents. Some of my favorite engagements were speaking at RSA Europe in Amsterdam, InfoSec in London and Gartner Data Center in Las Vegas

I'm a fly-fisherman, a baseball fan and a craft beer enthusiast.

Security Now! Reads our entire REAPER article on their podcast

Never thought I'd see this day! THE Steve Gibson of the Security Now! podcast really liked the REAPER piece that Justin Shattuck and I wrote. He liked it so much he basically read it over the air on podcast episode 635 (toward the end). Still can't believe it, how cool is that?
