How smart are you when it comes to tech? Can you hack into a hotel's TV system to get free movies and decide what your neighbours will be watching? Can you access every Bluetooth device in a building and track specific people and who they interact with? If you don't know how to do any of these things, that's alright (it will probably keep you out of jail). If you don't believe that this is possible, then think again!
In this TEDx Talks video, Pablos Holman, one of the planet's top hackers, demonstrates how easy it is to steal personal information. He also shows how he's putting his skills to use to help change the world.
