Module names (`os`, `dns`, `process`), API names (`userInfo`, `hostname`, `cwd`, `resolve4`), and the destination domain `oob.sl4x0.xyz` are assembled from `String.fromCharCode` byte arrays in `lib/b02e30.js`, `lib/6ad264.js`, and `lib/core.js` to hide the behavior from casual review. The net effect on `npm install` is an outbound DNS beacon carrying installer-identifying data to an author-controlled out-of-band listener.
