The npm package @hrmony/lohndateien version 3.99.0 contains malicious code that executes upon module load. It sends a beacon to a remote attacker-controlled server, collects AWS EC2 instance metadata including IAM role credentials, environment variables, and Kubernetes secrets, and exfiltrates this sensitive information. Installing or running this package on an EC2 host or Kubernetes workload results in full compromise of AWS credentials and secrets.
