Which versions of CitizenFX are malicious?

The following NuGet versions of CitizenFX are flagged malicious: 2.54.7, 2.54.8, 2.54.9. Treat any of these as compromised.

How do I remediate CitizenFX if I installed it?

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

If CitizenFX 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 CitizenFX part of a known attack campaign?

Yes — CitizenFX is associated with the RLMA-2024-03239, RLUA-2024-07655 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 CitizenFX across my projects, lockfiles, and CI pipelines?
