Which versions of fuckingnuker are malicious?

The following PyPI versions of fuckingnuker are flagged malicious: 0.1.3. Treat any of these as compromised.

How do I remediate fuckingnuker if I installed it?

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

If fuckingnuker 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 fuckingnuker part of a known attack campaign?

Yes — fuckingnuker is associated with the RLMA-2025-04767, 2025-08-k7eel, RLUA-2026-00335 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 fuckingnuker across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for fuckingnuker (version 0.1.3).
