Which versions of fiinquantx are malicious?

The following PyPI versions of fiinquantx are flagged malicious: 0.1.0, 0.1.1, 0.1.2, 0.1.3, 0.1.4, 0.1.5. Treat any of these as compromised.

How do I remediate fiinquantx if I installed it?

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

If fiinquantx 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 fiinquantx part of a known attack campaign?

Yes — fiinquantx is associated with the RLMA-2025-04166 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 fiinquantx across my projects, lockfiles, and CI pipelines?
