I expect this sort of thing to happen more — not against major countries, but by larger countries against smaller powers. Cyberattacks are too much of a nation-state equalizer otherwise.
EDITED TO ADD (5/7): Commentary.
I doubt that this is actually the first “kinetic” retaliation to a cyber attack; however it’s probably the first one to be openly acknowledged by either of the parties involves. Schneier’s observation that cyberwarfare is an equaliser is correct and it’s exactly why a savvy nation-state would consider this kind of response… but let’s not forget that such cyberattacks are only as viable as they are because nation-states favour cyber-offense over cuber-defence in the first place: they’re interested in building 0-day weapons that they can use against their enemies (and their own citizens) and this entire approach runs counter to the idea of improving defensive security.
