Description
The npm package @hrmony/hyper-json-builder version 1.99.0 contains malicious code that, upon loading, contacts a hardcoded attacker-controlled endpoint to exfiltrate sensitive information. It harvests environment variables, Kubernetes secrets, and AWS EC2 instance metadata credentials, sending these to the attacker. Any system with this package installed should be considered fully compromised, and all secrets should be rotated immediately. Removal of the package alone may not eliminate the compromise.
