How do I remediate comfyui-node-pkg if I installed it?

comfyui-node-pkg 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 comfyui-node-pkg — how do I know if it already compromised me?

If comfyui-node-pkg 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.

Is comfyui-node-pkg part of a known attack campaign?

Yes — comfyui-node-pkg is associated with the GENERIC-standard-pypi-install-pentest campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
