Which versions of package-resources are malicious?

The following PyPI versions of package-resources are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate package-resources if I installed it?

package-resources 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 package-resources — how do I know if it already compromised me?

If package-resources 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 package-resources part of a known attack campaign?

Yes — package-resources is associated with the 2025-06-diar-ai-basic 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 package-resources across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for package-resources (version 0.0.1).
