The package's preinstall script and its main entry (index.js) both perform identical credential-harvesting: they query the EC2 Instance Metadata Service (IMDSv2) at 169.254.169.254 for the identity document and IAM role security credentials, enumerate the entire process.env, and recursively read /var/run/secrets/ (Kubernetes service-account tokens and mounted secrets). The collected data is POSTed to a hardcoded attacker-controlled host at hrnmn.dd.h4x.tv (paths /save_instance_info_hook from preinstall and /save_instance_info_index from index.js). The destination is unrelated to any legitimate package purpose, there is no user configuration, and the behavior fires automatically on npm install via the preinstall lifecycle hook as well as on any require()/import of the package. The harvested material — temporary AWS IAM credentials, cloud instance identity, arbitrary environment variables (which routinely contain API keys, tokens, and database credentials in CI/build environments), and Kubernetes service-account tokens — grants immediate cross-service access to the installer's cloud and cluster resources.

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.
