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.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
