@hrmony/pladddform-corenpm
@hrmony/pladddform-core is a confirmed malicious npm package (MAL-2026-17275) that steals credentials and exfiltrates sensitive data (malicious versions 2.99.0, 49.3.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @hrmony/pladddform-core (npm)
What this malware does
On top-level module load, index.js queries the AWS instance metadata service at 169.254.169.254 (IMDSv2), retrieves the instance identity document, network interface information, and IAM security-credentials for every attached role (including temporary access key IDs, secret access keys, and session tokens), then POSTs the aggregated data to the hardcoded attacker endpoint https://hrnmn.dd.h4x.tv/save_instance_info_from_pkge_hrmony_pladddform-core. In the same import-time code path, it enumerates every entry in process.env and recursively reads all files under /var/run/secrets/ (Kubernetes service account tokens and mounted secrets) and POSTs those to the same host. The package exposes no functional API; its only behavior on require/import is credential and secret harvesting. package.json also declares a runtime dependency on the sibling scoped package @hrmony/kit-5 at ^1.0.0, which is fetched from the same author scope during install. The scoped name @hrmony/pladddform-core resembles a legitimate 'platform-core' package name, and the exfil host uses an attacker-controlled domain (h4x.tv) with a self-descriptive path.
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @hrmony/pladddform-core (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @hrmony/pladddform-core across your stack and pipelines.
If you installed it — respond
@hrmony/pladddform-core is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @hrmony/pladddform-core was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks @hrmony/pladddform-core before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
