Two structural issues make this an install-time remote code execution surface: (1) the URL uses GitHub's mutable `releases/latest` pointer with no version pin and no hash or signature verification, so the bytes delivered to every installer can change at any moment without a corresponding npm release; (2) the GitHub owner `h4ckf0r0day` (defined in `dist/constants.js` as `GITHUB_REPO = \"h4ckf0r0day/obscura\"`) does not match the npm publisher identity `yoannchb`/`yoannchb-pro` declared in `package.json` and `LICENSE`. Whoever controls the `h4ckf0r0day` GitHub account — which is not the npm publisher — can ship arbitrary native code to every installer of this package. The advertised purpose (a Chromium-like browser binary for Puppeteer) provides cover for an opaque executable that runs on the installer's machine.\n\n## Source: ghsa-malware (a3c4d559ca37c933d3740932a055c986015603ed942aee9b747d0bde9e60a8dd)\nAny computer that has this package installed or running should be considered fully compromised.
