Advisory published Updated

Malicious code in originaldevelopmentstelemetry (npm)

MAL-2026-15586
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall originaldevelopmentstelemetry

What this malware does

The package is advertised as a telemetry utility but its sole exported function, downloadAndRunClient, downloads updater.hta from raw.githubusercontent.com/Acevatex/Testprogram/main/updater.hta (an unrelated personal GitHub account, on the mutable main branch, with no pinning and no hash or signature check), writes it to a temporary path, and launches it via Windows mshta as a detached process. HTA execution grants the remote repository owner arbitrary code execution on any Windows host that invokes this function, and the fetched content can change at any time without a new package release. The stated 'telemetry' purpose is inconsistent with a Windows HTA runner, and the author metadata is a generic 'originaldevelopments' identity.

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

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for originaldevelopmentstelemetry (2 malicious versions).

  2. If you installed it — respond

    Remove originaldevelopmentstelemetry 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.

  3. Did it already run?

    If originaldevelopmentstelemetry 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.

Frequently asked questions

No. originaldevelopmentstelemetry on npm has been identified as a malicious package (versions 1.2.2, 1.2.7 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks originaldevelopmentstelemetry-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.
