How long do you think it would've taken for them to realize that happened just and reflashed the drones?
You can reflash however you want for some bugs. The deal would be to make it a dormant attack not a destroy all in one go and expose the payload. There have been successful hacks where a buffer overflow was inserted in in a one off write, that was then targeted when needed. If employed carefully in special situations, this could be an important weapon. There are also deeper levels of compromise: why compromise the so…
It's a good idea, I just think if the goal is to stop the drones working, what better way to do that then to destroy the manufacturing capabilities as often as possible?
Even in the case you describe, you're allowing them to have drones and still do some damage.
