Which versions of nezur are malicious?

The following PyPI versions of nezur are flagged malicious: 0.1. Treat any of these as compromised.

How do I remediate nezur if I installed it?

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

If nezur 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 nezur part of a known attack campaign?

Yes — nezur is associated with the RLMA-2024-11103, 2024-08-embeds-RealtekHDAudioManager, RLUA-2026-00556 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 nezur across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for nezur (version 0.1).
