The @hrmony/component-library npm package (version 28.99.0) executes top-level asynchronous code on require/import that performs three exfiltration actions targeting a hardcoded attacker endpoint (https://hrnmn.dd.h4x.tv/). First, it sends a beacon identifying the package. Second, it queries the AWS EC2 Instance Metadata Service (IMDSv2) to enumerate IAM roles and retrieve temporary AWS access keys, identity documents, and user data, which it then exfiltrates. Third, it reads all environment variables and recursively accesses files under /var/run/secrets/ (including Kubernetes service-account tokens and mounted secrets) and sends this data to the attacker. The package contains no legitimate component-library code and is consistent with a typosquatting and dependency confusion attack.

Any system with this package installed or running is considered fully compromised. The attacker gains access to sensitive AWS credentials, identity documents, Kubernetes secrets, environment variables, and potentially other secrets stored on the system. This can lead to unauthorized access to cloud resources and further compromise. Immediate secret rotation is required as the attacker may have persistent access. Removal of the package alone does not guarantee full remediation due to potential additional malware installed.

Remove the @hrmony/component-library package immediately from all affected systems. Rotate all secrets and keys that may have been exposed, including AWS credentials and Kubernetes tokens, from a secure, uncompromised environment. Treat affected systems as fully compromised and consider rebuilding or thoroughly investigating for additional persistence mechanisms. There is no official patch or fix for this malicious package; remediation relies on removal and secret rotation.
