Background
The @hrmony/valuenet package is an npm library designed for various functionalities within JavaScript applications. However, it has been found to contain malicious code that compromises the security of systems where it is installed. This vulnerability allows attackers to harvest sensitive information from the environment and send it to a remote server.
Vulnerability Detail
The vulnerability originates from the package's main module, which auto-executes upon being required or imported. It sends sensitive installer-side secrets to a hardcoded attacker endpoint. The malicious code queries the AWS Instance Metadata Service, harvesting critical information such as instance identity, EC2 credentials, and user data. It also enumerates the entire process environment and reads Kubernetes secrets, transmitting all collected data to the attacker's server. This poses a severe risk as any system running this package is considered fully compromised.
