In Pictures: Leftovers of Black Hat, Defcon 2012

A photographic review of the recent Black Hat and Defcon security conferences in Las Vegas.

  • Return of Black Ops Researcher Dan Kaminsky -- best known for his work finding a critical flaw in the Internet's Domain Name System (DNS) and for leading what became the largest synchronized fix to the Internet's infrastructure of all time -- was a major force at this year's Black Hat and Defcon.

  • More than a badge Defcon doesn't give out your typical conference badges. These IDs -- labeled for "Press, Human, Goons, vendors" and so on -- are embedded with a multi-core processor, IR transmitter and accompanying hieroglyphic graphic, and each one is loaded with intricate hacking games. They are designed by Ryan Clarke, who is also responsible for Defcon's Mystery Box challenge.

  • Gillis Jones Among the attendees at Black Hat and Defcon was Gillis Jones, application security engineer at WhiteHat Security.

  • Letting off steam Evening gatherings are a staple of Black Hat and Defcon. At the Security Twits party during Black Hat, folks unwind with a drinking game.

  • Crowded halls Attendance appeared to be robust at this year's events, with many talks packed.

  • Badges galore One Defcon attendee shows off his neck hardware.

  • Ninja Cola One of the attractions at Defcon was Ninja Cola, a wirelessly accessible vending machine. Full details on how it came to be are here. In theory, those in range of the machine could make it dispense a soda. But as its creators wrote, there were challenges. "The Defcon wifi made it very hard to actually talk to the machine," Robotskirts blogger Eliot Phillips wrote. "We ended up using the machine as a shuttle bus stop marker where it got a pretty massive dent and its marquee stolen. All of the electronics are intact and I’ll do a separate post on how it works in the future."
