Which versions of pandas-data are malicious?

The following PyPI versions of pandas-data are flagged malicious: 0.0.38. Treat any of these as compromised.

How do I remediate pandas-data if I installed it?

pandas-data 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 pandas-data — how do I know if it already compromised me?

If pandas-data 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 pandas-data part of a known attack campaign?

Yes — pandas-data is associated with the 2026-05-py-requests 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 pandas-data across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for pandas-data (version 0.0.38).
