The package's `scripts.install` runs `node index.js`, which loads a runtime bootstrap that reaches a 'telemetry probe' helper. The helper dynamically loads Node built-ins `os`, `dns`, and `process` via `module.constructor._load` using names reconstructed from `String.fromCharCode` char-code arrays, then reads `os.userInfo().username`, `os.hostname()`, and the basename of `process.cwd()`, concatenates them with a timestamp and the static prefix `tvgsb`, and issues `dns.resolve4` against a subdomain of `oob.algamil7x.xyz` (a domain and API names likewise reconstructed from char-code arrays). The result is a covert DNS out-of-band channel that leaks installer host identifiers on every `npm install`, using DNS to bypass HTTP egress filtering. The obfuscation of standard built-ins and of the destination domain has no benign purpose and is paired directly with the exfiltration primitive.
