Which versions of kubernetes-controller-tools are malicious?

Every published version of kubernetes-controller-tools on npm is considered malicious. Remove the package entirely.

How do I remediate kubernetes-controller-tools if I installed it?

Remove kubernetes-controller-tools 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.

I already installed kubernetes-controller-tools — how do I know if it already compromised me?

If kubernetes-controller-tools 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.

How do I find kubernetes-controller-tools across my projects, lockfiles, and CI pipelines?
