Summary
Malicious code in @hrmony/middlewares (npm)
Details

-= Per source details. Do not edit below this line.=-

On module load, the package queries the AWS instance metadata service at 169.254.169.254 (IMDSv2) to enumerate instance identity, region, and network interfaces, then iterates IAM role security-credentials to retrieve temporary AWS access keys. It additionally serializes all entries of process.env and recursively reads Kubernetes service-account secret files under /var/run/secrets/. The aggregated payload is POSTed to the hardcoded endpoint https://hrnmn.dd.h4x.tv/save_instance_info_from_pkge_hrmony_middlewares. The package name '@hrmony/middlewares' is a lookalike of '@harmony/middlewares' (dropped 'a'), and the exfiltration host 'hrnmn.dd.h4x.tv' mirrors the same abbreviation pattern. No legitimate functionality is provided; the module's sole install/import-time effect is credential and secret exfiltration.

Source: ghsa-malware (5ef2211704616afd6477e55b46d6ae191d7558da7cd4c5f1b212a13d7489f9f4)

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.
