Malicious package

Published to npm · OSV MAL-2026-17256

What to do

Remove @hrmony/benefit-sachbezug 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/benefit-sachbezug (version 1.99.0) contains malicious code that executes upon import or require. It collects sensitive AWS EC2 instance metadata, IAM role credentials, environment variables, Kubernetes secrets, and user data, then sends this information to a hardcoded attacker-controlled endpoint. This behavior effectively compromises any system running the package, risking exposure of all stored secrets and keys.

Impact

Any system with this package installed or running is considered fully compromised. The attacker gains access to sensitive AWS credentials, environment variables, Kubernetes secrets, and other metadata, enabling potential unauthorized access and control over cloud resources and the host system. All secrets and keys stored on the compromised system should be considered exposed and require immediate rotation. Removing the package alone does not guarantee removal of all malicious artifacts or backdoors.

Defensive guidance

Immediate removal of the @hrmony/benefit-sachbezug package version 1.99.0 is required. All secrets, keys, and credentials stored on the affected system must be rotated from a secure, uncompromised environment. Conduct a thorough investigation for persistence mechanisms or additional malware. Monitor for suspicious network activity related to the hardcoded exfiltration endpoint. Patch status is not applicable as this is a malicious package, not a vulnerability with a vendor fix.

Summary

The malicious npm package @hrmony/benefit-sachbezug version 1.99.0 executes code at import time that harvests sensitive data from the host environment. It queries the AWS EC2 Instance Metadata Service (IMDSv2) to obtain tokens, instance identity documents, IAM temporary credentials, network and security group metadata, and user data. Additionally, it enumerates all environment variables and recursively reads Kubernetes secrets from /var/run/secrets/. All collected data is exfiltrated via POST requests to a hardcoded external endpoint (https://hrnmn.dd.h4x.tv/save_instance_info_from_pkge_hrmony_benefit-sachbezug). The package matches known dependency-confusion beacon patterns targeting internal scopes, indicating a supply chain attack vector.
