When you do that to a nation about their classified intel, it's called espionage. It's a biiiit more serious than a social media hack.
In practical terms, espionage can affect thousands of lives directly and change the course of a war. Imagined the shitshow if someone released that kind of info now. It could jeopardize the Ukraine conflict. It's treated as more serious than murder because it can be.
