Summary
Malicious code in babel-eslint-parser-legacy (npm)
Details
Package name `babel-eslint-parser-legacy` is a one-suffix confusion against the legitimate `babel-eslint-parser`. The package's own `main` is an empty stub, so it provides no functionality of its own. Its `package.json` declares a single runtime dependency `ltidisafe` pointing at a direct HTTPS tarball URL — `https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.1.8.tgz` — hosted on a Google Cloud Storage bucket unaffiliated with Babel and outside the npm registry. On `npm install`, npm fetches and installs the contents of that tarball into the installer's `node_modules`, executing any lifecycle scripts it declares. The tarball bytes are attacker-mutable (the bucket owner can swap contents at any time), are not subject to npm registry scanning, and are not pinned by integrity hash in the manifest. The typosquat name is the lure; the external-URL dependency is the smuggling vector for arbitrary attacker-controlled code into the installer's dependency tree.
