transform-es2015-unicode-regex @6.24.1

Summary

package.json declares the package's own name as a dependency (and devDependency) with the specifier http://pack.nppacks.com/npm/transform-es2015-unicode-regex, a plain-HTTP, non-registry, third-party host unrelated to the legitimate babel-plugin-transform-es2015-unicode-regex it name-resembles. When a consumer runs npm install , npm fetches whatever tarball that URL currently returns and installs it, running any lifecycle scripts and making the fetched code require-able — arbitrary install-time code execution controlled by the operator of pack.nppacks.com, over an unauthenticated cleartext channel that is also trivially MITM-able. The package's index.js is not the referenced Babel plugin's code and carries a self-labeled 'Security Research Testing Purpose' comment; the name mimics babel-plugin-transform-es2015-unicode-regex, increasing the chance of accidental installation.
