Summary

The package publishes under the name of the legitimate better-tailwindcss project but its package.json declares both a runtime and dev dependency on better-tailwindcss resolved from http://pack.nppacks.com/npm/better-tailwindcss — a plain-HTTP, non-registry host with no integrity hash and no TLS. On npm install , npm fetches and installs that arbitrary, mutable tarball, and any install/postinstall scripts inside it execute on the installer's machine. The shipped code itself is a Babel plugin clone unrelated to the real better-tailwindcss project (a tailwind ESLint plugin) and carries a self-label describing the package as being for 'Security Research Testing Purpose,' confirming it is a namespace squat used as a delivery vehicle for code hosted at pack.nppacks.com.
