TL;DR · WeSearch summary

The same maintainer owns cacheable (29M downloads/month), flat-cache (565M downloads/month), file-entry-cache (557M downloads/month), and several other widely-used caching utilities, all of which were swept up in the same attack. Anyone who ran npm install against an affected version would have had setup.mjs execute automatically before their install completed.setup.mjs is a heavily obfuscated dropper. Extracts authToken values and any //registry.*:_authToken=... entries.
