Which versions of kimportsetup are malicious?

The following PyPI versions of kimportsetup are flagged malicious: 0.1.1. Treat any of these as compromised.

How do I remediate kimportsetup if I installed it?

kimportsetup 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 kimportsetup — how do I know if it already compromised me?

If kimportsetup 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 kimportsetup part of a known attack campaign?

Yes — kimportsetup is associated with the RLMA-2025-04783, 2025-08-k7eel, RLUA-2026-00453 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find kimportsetup across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for kimportsetup (version 0.1.1).
