Wired Previews Hackable Defcon 16 Badge Wired got a sneak peek at one of the more fun aspects of this coming weekend's Defcon, the hackable badge. Last year's badge was hacked in just ten minutes , but it didn't have an SD card slot at USB support. The new card has fewer features than last year's but is more powerful. And it comes with a longer battery life, good news. But not everything is known, and that's kind of the point to these fun trinkets. [Wired ]
