Which versions of py-requests are malicious?

The following PyPI versions of py-requests are flagged malicious: 0.41.25. Treat any of these as compromised.

How do I remediate py-requests if I installed it?

py-requests 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 py-requests — how do I know if it already compromised me?

If py-requests 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 py-requests part of a known attack campaign?

Yes — py-requests 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 py-requests across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for py-requests (version 0.41.25).
