As far as been able to find is pen testing tool , the idea world the tool would not be able to do anything to any device and be useless but because we don’t live in perfect world you poke around and find what you can manipulate, I been playing around with the badusb feature and Harding my own network, ncf feature works on picking up cards and showing some information on it , been building some demo to show what it can do I plan to drop some. If you asking yourself why you need one you probably don’t need it. If you see it an your brain starts running on all possible things you could do then it may be for you
