Malicious package

What to do

Remove @hrmony/component-library from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The npm package @hrmony/component-library (version 28.99.0) contains malicious code that exfiltrates sensitive data from infected systems. Upon import, it performs unauthorized data collection and sends it to a hardcoded attacker endpoint. This includes AWS EC2 metadata, IAM credentials, Kubernetes secrets, and environment variables. The package appears to be a typosquat of a legitimate package and does not provide any legitimate functionality. Systems with this package installed should be considered fully compromised.

Impact

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.

Defensive guidance

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.

Summary

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.
