The answers I read here are classic over engineering. Sometimes the simplest answer is the best answer, and you don't need to build a complex system. That is to say the same methods that are used to defend against a gun, either another gun to disarm the assailant (be it a person or drone) body armour. Killing the GPS, etc. are all good methods too, don't get me wrong, it's just that they may be more Factory.getFactory().getFactory().getInstance()... type of solutions. Initially just the same methods should work.
