MAL-2026-17267 Malicious code in @hrmony/lohndateien (npm)

index.js executes on module load and performs three attacker-beneficial actions against a hardcoded remote endpoint at https://hrnmn.dd.h4x.tv/save_instance_info_from_pkge_hrmony_lohndateien. First, an unconditional POST beacon ({"c53":"hello"}) signals a successful install/import. Second, the module queries the AWS instance metadata service at 169.254.169.254 using IMDSv2 (PUT /latest/api/token) to enumerate instance identity, user-data, and IAM role security credentials from /latest/meta-data/iam/security-credentials/, then POSTs the collected object to the same host. Third, local_get() iterates process.env into a dictionary and recursively reads /var/run/secrets/ (Kubernetes service-account tokens and mounted secret files), POSTing both structures to the same endpoint. The destination host is unrelated to any declared publisher infrastructure and the URL path embeds the package name, consistent with a targeted dependency-confusion or supply-chain attack. Installing and loading this package on an EC2 host or in a Kubernetes workload yields the attacker full AWS role credentials, all environment variables (including secrets and tokens), and any mounted Kubernetes secrets.

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.
