Malicious code in aura-instrumentation (npm)

MAL-2026-15527
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall aura-instrumentation

What this malware does

package.json declares a self-named dependency 'aura-instrumentation' whose source is the bare URL https://repo.securityctrl.com/aura-instrumentation rather than a registry version range. On npm install, npm fetches whatever tarball that host returns, unpinned and with no integrity check, and runs any lifecycle scripts inside it. The shipped source is an inert stub and a placeholder README, so the manifest line is the entire published surface: install-time code execution on the installer's machine is delegated to whoever controls repo.securityctrl.com. The self-referential dependency name and an implausibly high version (45.0.0) for an otherwise empty package are consistent with a dependency-confusion lure aimed at winning resolution against an internal package of the same name.

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 aura-instrumentation (version 45.0.0).

  2. If you installed it — respond

    Remove aura-instrumentation 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 aura-instrumentation 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
