Which versions of huggingface-hubs are malicious?

The following PyPI versions of huggingface-hubs are flagged malicious: 95.6. Treat any of these as compromised.

How do I remediate huggingface-hubs if I installed it?

huggingface-hubs 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 huggingface-hubs — how do I know if it already compromised me?

If huggingface-hubs 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 huggingface-hubs part of a known attack campaign?

Yes — huggingface-hubs is associated with the 2024-11-byted-dast 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 huggingface-hubs across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for huggingface-hubs (version 95.6).
