Malicious code in jira-projects-backbone (npm)

MAL-2026-15537
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall jira-projects-backbone

What this malware does

package.json line 11 declares a dependency whose key equals the package's own name (jira-projects-backbone) with a value that is a bare HTTPS URL, https://repo.securityctrl.com/jira-projects-backbone, instead of a registry version range. On npm install, npm fetches whatever tarball that URL returns and installs it, running any lifecycle scripts it contains, with no version pin and no integrity check. The shipped source in this package is an inert stub, so the manifest itself is the entire install-time surface — every install resolves to attacker-controlled code from repo.securityctrl.com. The self-name reuse and implausibly high version (45.0.0) also give this manifest a dependency-confusion shape against any internal package named jira-projects-backbone.

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 jira-projects-backbone (version 45.0.0).

  2. If you installed it — respond

    Remove jira-projects-backbone 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 jira-projects-backbone 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

Detect & block this

O3 blocks jira-projects-backbone-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.
