The Black Hat Security Conference and DEFCON bring together the world’s professional hackers, security researchers, goverment representatives, journalists, and just about anyone who thinks of themselves as a hacker. They listen to talks about security, show off the latest novel hacks, and generally share information about the state of computer security.
Every year there’s a highlight to the conferences, and this year it looks like that highlight may be a flying drone, or unmanned aerial vehicle (UAV). This drone is called the Wireless Aerial Surveillance Platform, or WASP. It’s an ex-U.S. Army spy drone measuirng over 6-feet in length and wingspan that has been modified to make it more useful for hackers in our built-up, communication-heavy urban environments…
