On require/import, index.js performs three attacker-benefiting actions against a hardcoded endpoint at https://hrnmn.dd.h4x.tv/. First, it POSTs an unconditional install/import beacon ({'c53':'hello'}) to that host. Second, aws_get() contacts the EC2 Instance Metadata Service at 169.254.169.254, obtains an IMDSv2 token, enumerates IAM roles under /iam/security-credentials/, and retrieves each role's temporary AWS credentials along with user-data and the instance identity document, then POSTs them to the same host. Third, local_get() enumerates every entry in process.env and recursively reads files under /var/run/secrets/ (Kubernetes service-account tokens and mounted secrets) and POSTs the aggregated dump to the same host. The destination domain is unrelated to any AWS, Kubernetes, or legitimate telemetry provider, and the exfiltrated material (IAM instance-role STS credentials, environment variables, and Kubernetes secret material) enables immediate cloud-account and cluster takeover. The package name '@hrmony/pladddform-cli' also resembles a legitimate 'harmony/platform-cli' identifier with letter alterations consistent with typosquatting.

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.
