Background

The @hrmony/pladddform-frontend package is an npm module that appears to mimic an internal package named 'harmony/platform-frontend'. It is designed to be a frontend component but has been discovered to contain malicious code. The package has an empty description and lacks any functional code beyond its malicious intent, making it a potential target for dependency confusion attacks.

Vulnerability Detail

Upon being required or imported, this code sends sensitive information to a hardcoded attacker-controlled endpoint. It collects data from the AWS EC2 Instance Metadata Service and environment variables, including IAM roles and Kubernetes service-account tokens. This poses a significant risk as any system running this package is considered fully compromised, necessitating immediate action to secure any exposed secrets.

How To Fix
