Which versions of swapoc are malicious?

The following PyPI versions of swapoc are flagged malicious: 0.0.1, 0.0.2, 0.0.3, 0.0.4, 0.0.5, 0.0.6, 0.0.7, 0.0.8, 0.0.9, 1.0.0, 1.0.1, 2.0.0. Treat any of these as compromised.

How do I remediate swapoc if I installed it?

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

If swapoc 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 swapoc part of a known attack campaign?

Yes — swapoc is associated with the RLMA-2025-00530, GENERIC-simple-tests, RLUA-2026-00792 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 swapoc across my projects, lockfiles, and CI pipelines?
