Malicious code in intuit-authz (npm)

MAL-2026-15511
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall intuit-authz

What this malware does

package.json at line 11 declares a self-named dependency intuit-authz whose source is the bare HTTPS URL https://repo.securityctrl.com/intuit-authz instead of a semver range resolved through the npm registry. On npm install, npm fetches whatever bytes that URL currently serves and installs them, running any lifecycle scripts contained in the fetched tarball. The reference is unpinned, has no integrity hash, and points at a host unrelated to Intuit's published domains, so the operator of repo.securityctrl.com controls code executed on every installer's machine. The self-named key (intuit-authz declaring intuit-authz as a dependency) combined with a version number (55.0.0) implausibly high for a package under this name matches the dependency-confusion shape targeting an internal Intuit authorization package.

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 intuit-authz (version 55.0.0).

  2. If you installed it — respond

    Remove intuit-authz 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 intuit-authz 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 intuit-authz-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.
