Which versions of py-corfd are malicious?

The following PyPI versions of py-corfd are flagged malicious: 1.0.0. Treat any of these as compromised.

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

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

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

Yes — py-corfd is associated with the RLMA-2024-04394, RLUA-2024-08827 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 py-corfd across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for py-corfd (version 1.0.0).
