Aye, the basic concept was covered in this a couple of decades ago - https://en.wikipedia.org/wiki/The_Killing_Star https://en.wikipedia.org/wiki/The_Killing_Star (which has just about as dark a conclusion as Cixin's trilogy does), but it was the actual Dark Forest name specifcially I thought existed prior. Clearly I'd been unwittingly absorbing output from people who'd already read his books ahead of me! - ed oh! I see The Killing Star's mentioned in the original linked article. It's worth a read, if you haven't already.
