Yeah some big name in the homebrew scene looked at it and it was having high resource usage and some network traffic indicating it most likely does have a miner in it.
I saw something about that and assumed it was an April Fool's joke, but... no.
From what I've read we don't yet have absolute proof this is what's happened, but the accusations are there and we're yet to see what the investigation will bring up. What a weird world we live in if it turns out to be true.
I wonder if this is the game that uses your switch to mine cryptocurrency
