Which versions of rizco09 are malicious?

The following PyPI versions of rizco09 are flagged malicious: 0.1.0. Treat any of these as compromised.

How do I remediate rizco09 if I installed it?

Remove rizco09 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 rizco09 — how do I know if it already compromised me?

If rizco09 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 rizco09 part of a known attack campaign?

Yes — rizco09 is associated with the RLMA-2025-05635, 2025-10-wangzhou183, RLUA-2026-00724 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 rizco09 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for rizco09 (version 0.1.0).
