The scanner thing is nothing new, although DJI’s trying to sell it to government agencies is. Unless signal encrypted, everything involved with the command/control and video transmissions to and from an RC aircraft can be intercepted and viewed by anyone using receivers on the correct frequencies. A simple scanner provides all the frequency info needed to initiate data reception. Such was the case with al Qaida and the Taliban until the military switched to digital encrypted comms for their drones. OTOH, DJI is making a clear statement they’ll do anything for a buck, and the allegations their systems transmit lots of data were true.
DJI’s news just gave people a reason to develop more secure systems, establishing a new revenue stream for manufacturers. What’s funny about this is DJI’s acting like their products are new, break through technologies. Everything they have done to date was done by government affiliated groups a long time ago.
