Hackers able to turbo-charge DJI drones way beyond what's legal

Drone hackers in the UK are busy at work exploiting the application security shortcomings of a major manufacturer to circumvent restrictions, including flight elevation limits. DJI says it has pushed out a firmware update to nip the problem in the bud, but one expert The Register spoke to maintains that hacking is still possible.
The potential for drone hacking can be traced back to a mistake made by DJI in leaving development debug code in its Assistant 2 application. Changes could be made by commenting out one line in a file and setting the debug flag from false to true. The shortcoming exposed a full range of parameters that enabled hackers to turn off safeguards.

Apparently this is mostly about European drones and laws, so I don't know how relevant it is to North American drones.
Until seeing this article, it did not occur to me that hacking the software would be worth the effort.
Just shows to go ya, don't misunderestimate the creativeness of people on a "mission".
