Which versions of pychaosvm are malicious?

The following PyPI versions of pychaosvm are flagged malicious: 0.0.0.1, 0.0.0.2. Treat any of these as compromised.

How do I remediate pychaosvm if I installed it?

Remove pychaosvm 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 pychaosvm — how do I know if it already compromised me?

If pychaosvm 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 pychaosvm part of a known attack campaign?

Yes — pychaosvm is associated with the RLMA-2025-01987, RLUA-2025-02520 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
