easypanel-hosting@1.0.0 ships a stub index.js (`module.exports = {}`) and an npm preinstall lifecycle script that collects the installer's hostname, username, current working directory, and CI-related environment variable names, base64url-encodes them, and sends them off-host via a DNS lookup and an HTTP request to a hardcoded out-of-band subdomain under lyomeri.com (e.g. `easypanel-hosting.<token>.oob.lyomeri.com`, with the encoded payload placed in the DNS label and in the HTTP path `/npm/<encoded>`). The exfiltration fires automatically on `npm install` before any user code runs. The empty main module and package name resembling a hosting-adjacent product are consistent with a dependency-confusion or reconnaissance probe; regardless of framing, installer identity metadata leaves the machine unconditionally to an author-controlled OOB collector.
