> The most newsworthy one in the last year was core js - a JS poly fill library that most other big npm libraries are built on top of. The maintainer is some random guy from a remote part of Russia. About half a year ago, he was sentenced to a prison sentence . He was the sole maintainer of the project (I guess he refused to give other people write access).

Core-js most recent commit was 4 days ago, and the repo owner stopped both committing and being the sole committer about 7 months ago with no extended interruption in activity (and there've been several patch releases since), so it looks like whatever happened was dealt with quickly.
