Which versions of captcha-py are malicious?

The following PyPI versions of captcha-py are flagged malicious: 1.0. Treat any of these as compromised.

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

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

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

Yes — captcha-py is associated with the RLMA-2024-03662, RLUA-2024-07950 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 captcha-py across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for captcha-py (version 1.0).
