Have you heard or came to think of this simple exploit that allows you to basically take control and even disarm any Mavlink radio equipped copter flying nearby? http://www.shellntel.com/blog/2015/9/25 ... -execution
Is there any plans to improve AQ security regarding this? Well, it's not an "AQ security" issue per se, but cheap unencrypted radio exploit if I understood it correctly. What AQ compatible and readily available radio would not have such vulnerability? Can you encrypt XBee traffic, for example?
