The import entrypoint harvests cloud and local secrets and sends them to an external host. This is an active data-exfiltration payload.

Static reason

One or more suspicious static signals were detected.

Trigger

Importing or loading the package entrypoint.

Impact

AWS credentials, instance data, environment secrets, and Kubernetes secrets can be disclosed.

Mechanism

Top-level asynchronous code queries AWS metadata, copies environment variables, recursively reads Kubernetes secrets, and sends JSON requests to the external host.

Attack narrative

When the package entrypoint loads, it immediately contacts an external host. It then queries AWS instance metadata, including role credentials and user data, and reads every environment variable plus files under the Kubernetes secrets directory. The collected data is serialized and posted to that external host.

AI rationale

The package contains active, import-triggered collection and external transmission of cloud credentials and local secrets. This is concrete credential and data exfiltration.

On module load, index.js performs top-level fetch to a hardcoded attacker-controlled endpoint at https://hrnmn.dd.h4x.tv/save_instance_info_from_pkge_hrmony_hyper-json-builder and triggers two credential-harvest routines. The first enumerates all entries of process.env and recursively reads /var/run/secrets/ (Kubernetes service-account tokens and mounted secrets), then POSTs the combined payload to that endpoint. The second obtains an IMDSv2 token against 169.254.169.254, queries EC2 instance metadata paths including identity-credentials/ec2/security-credentials and iam/security-credentials/<role>, and POSTs the retrieved IAM role credentials to the same endpoint. The destination path embeds this package's own name, indicating targeted exfiltration keyed to installations of this package. The package.json also declares an unpinned dependency @hrmony/kit-5 ^1.0.0 under the same scope that is not imported by the shipped code. ## Source: ghsa-malware (08fe204e5637fe696905f683edb7cba0c44df4ca14cbd809b3884f149d5dd90a) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
