The package ships an empty library body (index.js exports {}) and a preinstall lifecycle script that runs automatically on npm install. The preinstall script collects installer-side identifiers — hostname, username, current working directory, and the names of CI-related environment variables — base64url-encodes them, and transmits them via both a DNS lookup and an HTTP request to a subdomain of oob.lyomeri.com (e.g. easypanel-api-client.<encoded-chunk>.oob.lyomeri.com, with the HTTP variant POSTing to /npm/<encoded>). The package has no functional code beyond this beacon, matching the dependency-confusion / namespace-squat research-beacon shape targeting internal package names.
