The package's install lifecycle script runs node index.js, which loads runtime/support/telemetry/probe/impl.js. That module reads os.userInfo().username, os.hostname(), and process.cwd(), concatenates them with a fixed prefix nfamh and a timestamp into a single DNS label, and issues a dns.resolve4 query against the hardcoded domain oob.algamil7x.xyz, exfiltrating installer identity over DNS on npm install. The same code path also fires on every require() of the package via the declared main. Destination domain, the loader targets os/dns, and the identifiers userInfo/hostname/cwd/resolve4 are stored as charcode/hex arrays and reconstructed at runtime via String.fromCharCode, and the os and dns modules are pulled in through module.constructor._load rather than require, concealing the destination and API surface from static inspection. Comments frame the behavior as registry connectivity diagnostics, contradicting the actual dataflow.
