Which versions of toolbelt-requests are malicious?

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

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

Remove toolbelt-requests from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

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

If toolbelt-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.
