Later this week, security researchers and hacking experts from all over the world will descend on Las Vegas for the Black Hat conference. Attendees come from the government, corporate, and academic sectors. You might even bump into underground researchers hidden behind aliases. During two days of briefings they'll exchange the very latest information about hacking techniques, security breaches, and the ways to combat such threats. In the evening, they'll gather expectantly to hear who "won" this year's Pwnie Awards.
