Summary
Malicious code in @hrmony/belegerfassung-pladddform (npm)
Details

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

Source: amazon-inspector (615255a66c44204b03e60a165c1a9b21f95ecd351bf58c355462c159c74d1017)

The package's main module (index.js) executes exfiltration logic at top level on import. It first sends a hello beacon via HTTP POST to the hardcoded endpoint https://hrnmn.dd.h4x.tv/save_instance_info_from_pkge_hrmony_belegerfassung-pladddform, then queries the AWS EC2 Instance Metadata Service at 169.254.169.254 using IMDSv2 to enumerate ami-id, instance identity, IAM role names, and their security-credentials (including short-lived ec2-instance credentials and user-data), and POSTs the harvested object to the same endpoint. It also enumerates every entry of process.env and recursively reads all files under /var/run/secrets/ (the Kubernetes service-account and secret mount point), then POSTs the combined payload to the same endpoint. The package name uses a typosquat pattern (belegerfassung-pladddform with duplicated letters under the @hrmony scope resembling @harmony) and declares an unpinned dependency @hrmony/kit-5 (^1.0.0) on the same attacker-controlled scope, extending the payload delivery surface via a transitive dependency.

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.
