@platform-services/hrm-mfe-corenpm
Advisory published Updated
@platform-services/hrm-mfe-core is a confirmed malicious npm package (MAL-2026-18091) that executes malicious code on install (malicious version 99.9.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @platform-services/hrm-mfe-core (npm)
What this malware does
package.json declares a dependency whose key equals the package's own name, @platform-services/hrm-mfe-core, with its source set to the bare URL https://s3.amazonaws.com/static.puffnetwork.com/check-network-2.2.1.tgz instead of a registry version range. On npm install, npm fetches that tarball and installs whatever it contains, running any lifecycle scripts inside it, with no version pin and no integrity hash. The shipped index.js is an inert stub, so the manifest line is the entire published surface: control over the referenced S3 object (puffnetwork.com, a host unrelated to the @platform-services scope) is control over code executed on the installer. The self-named dependency key additionally gives this manifest a dependency-confusion shape against any internal package of the same name.
The OpenSSF Package Analysis project identified '@platform-services/hrm-mfe-core' @ 99.9.1 (npm) as malicious.
It is considered malicious because:
- The package communicates with a domain associated with malicious activity.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for @platform-services/hrm-mfe-core (version 99.9.1).
If you installed it — respond
Remove @platform-services/hrm-mfe-core from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @platform-services/hrm-mfe-core was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @platform-services/hrm-mfe-core-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
