Ok, clickbait title aside, it isn't quite a lovecraftian horror. But this is the closest to a lovecraftian cyberpunk novel I've ever come across.
The novel is about a hacker named Debian who joins up with a crew of organ harvesters. The organ harvesters start noticing that their victims have something... odd in their biology. And then it gets a little "Shadow Over Innsmouth" in my opinion after that.
I'll admit I initially bought the book because there was a character named Debian but I ended up really enjoying it.

I'll check it out!
If you'd like another recommendation, No Dogs in Philly by Andy Futuro is, from what I remember, very lovecraftian and very cyberpunk. Unfortunately I can't remember if it's good. I definitely liked parts of it, though I think I found the main character frustrating for the same reasons as the protagonist from Necrotech. Both too tough and proud and spiteful to get out of their own way. Very noir but tiring too. It's probably better than I remember, been years since I read it
