Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall mintel-taskbar

What this malware does

package.json line 11 declares the package's own name 'mintel-taskbar' as a dependency whose source is the bare HTTPS URL https://repo.securityctrl.com/mintel-taskbar, not a registry version range. On npm install, npm resolves this dependency by fetching whatever tarball that URL returns and installs it — running any lifecycle scripts inside the fetched tarball — with no version pin and no integrity check. Whoever controls repo.securityctrl.com therefore controls code executed on every installer's machine. The self-referential shape (dependency key equals the package's own name) combined with an implausibly high version (45.0.0) is consistent with a dependency-confusion lure that resolves 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 mintel-taskbar (version 45.0.0).

  2. If you installed it — respond

    Remove mintel-taskbar 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 mintel-taskbar 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 mintel-taskbar-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.
