Which versions of @oku-ui/checkbox are malicious?

The following npm versions of @oku-ui/checkbox are flagged malicious: 0.6.3. Treat any of these as compromised.

How do I remediate @oku-ui/checkbox if I installed it?

@oku-ui/checkbox is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed @oku-ui/checkbox — how do I know if it already compromised me?

If @oku-ui/checkbox 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 @oku-ui/checkbox across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for @oku-ui/checkbox (version 0.6.3).
