This ought to do it: https://en.wikipedia.org/wiki/Skynex . It is a real issue, though. Not because it's hard to protect any given target, but because protecting _all_ targets is more or less impossible.

Let's say you could protect yourself with the same model of drone, which you probably can't, but let's say you can. Where do you put those defense drones? The attacker gets to choose where the attack happens and you can't be ready _everywhere_. The real answer probably involves going on the offensive yourself.
