How far away do you think we are from consumer drones being used to commit a crime or terrorist attack?
What about a delivery drone being intercepted and robbed for its packages?
The idea is that you give the drone a target position and then it should control itself.
Security could be a lot better but most of the tools are made for internet transfers, so it is easier to just give them a wifi and then send commands to them via that.
With the current methods, cracking a wifi takes time. And a moving target, that is nearly impossible to crack the wifi and send a message to it, you have to know a lot of factors for this to be possible.
Some of them are just radio controlled though so guess it won't be hard to hijack those.
