Anyone droned in Sweden and got maliciously intercepted and deliberately shot down?

Recommended Posts

The most bizarre incident happened to us in Sweden. We were droning on one of the islands (not within the flight restrictions zone), when suddenly we lost all control over the drone, which had previously flown fine . 1st flight was uneventful and all was in full working order.  We changed a battery and took off again. There was 45% of battery still left, no issues with the signal and drone was at 0 point above our heads and we were just about to initiate landing procedures. Suddenly it just took off over the water and a witness claims that it flew towards another island. We lost all control over it and ground station was unable to detect any signal. Could it be that we got intercepted and shot down by someone? Is there any way one can detect someone with such technology nearby? How can one protect themselves from such incidents happening in the future? Thanks and regards!

Change the stock passwords that the UAS ships with is the first thing that you should do to secure your uplink between the RC and the UAS. DJI (and other manufacturers too I'm sure) have the same password on every unit that ships. With $100.00US of electronic parts off the shelf you can build a controller to hack drones in-flight. The most common exploit is people fail to change the stock passwords on the RC and then there are the wi-fi and BlueTooth pucks...

That is about the best you can do unless you want to invest in an RF Frequency analyser. (http://rfexplorer.com/models/) That would allow you to scan the local bandwidth and determine if there was something generating EMF that will interfere with your controller signal to the drone. I personally think that it is a drastic step unless you live or fly in an area that the RF spectrum is heavily used; especially in the 2.4GHz bandwidth.

Were you able to regain control?  Did you get the drone back?  What kind of drone?

if you were directly overhead there's a good chance that you lost signal and the drone went into failsafe. If that's the case, it depends on how you have the fialsafe setup.  Also if you traveled a significant distance from your previous flight, did you recalibrate the compass?

Is the password change in the Menu?

 

In the DJI GO app under the controller icon there is a four digit password to the right of the RC name field.
