Joe Grand, the owner of Grand Idea Studio and one of the former members of the L0pht hacking crew, has carved out a unique niche for himself in the security community. Known as a hardware security wizard, Grand has spent the last few years tinkering with all manner of devices and designing the badges for the annual Defcon conference. Right now, Grand is in the middle of filming for a new show called “Prototype This,” which premieres on the Discovery Channel on Oct. 15.
