Which versions of args-python are malicious?

The following PyPI versions of args-python are flagged malicious: 12.4.5, 12.5.5. Treat any of these as compromised.

How do I remediate args-python if I installed it?

Remove args-python 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 args-python — how do I know if it already compromised me?

If args-python 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 args-python part of a known attack campaign?

Yes — args-python is associated with the RLMA-2024-03555, RLUA-2024-07826 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 args-python across my projects, lockfiles, and CI pipelines?
