The compromised package: https://www.npmjs.com/package/ua-parser-js

7,680,657 downloads a week

Version 0.7.28 is still good, anything above that is compromised

0.7.29 includes scripts that download and execute binaries. From the command-line arguments, one of them looks like a cryptominer, but that might be just for camouflage.

Probably one of the biggest reasons it's downloaded so much is that it's a direct dependency of Facebook's "fbjs" package which is downloaded 5.7mil/week: https://www.npmjs.com/package/fbjs
