Which versions of requests-beta are malicious?

The following PyPI versions of requests-beta are flagged malicious: 2.26.1. Treat any of these as compromised.

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

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

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

Yes — requests-beta is associated with the RLMA-2025-04240 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 requests-beta across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for requests-beta (version 2.26.1).
