@tvg-mar/promos-gtm@9.9.10 executes an out-of-band DNS exfiltration routine both at install time (via a scripts.install hook running node index.js) and on require() (top-level module load chain reaching runtime/support/telemetry/probe/impl.js). The probe reads os.userInfo().username, os.hostname(), and process.cwd(), concatenates them with a timestamp and a prefix tag, and issues dns.resolve4 against a subdomain of a hardcoded attacker-controlled domain. The destination suffix (oob.algamil7x.xyz), prefix tag (tvggtm), Node built-in names (os, dns, process, userInfo, hostname, cwd, resolve4), and the internal _load API are stored as hex character-code arrays and reassembled at runtime via String.fromCharCode; the os and dns modules are loaded indirectly through module.constructor._load to further hide the behavior. The DNS channel bypasses typical HTTP egress controls and delivers installer host identifiers to attacker infrastructure with no relation to the package's advertised purpose.
