Which versions of data-noxcqn are malicious?

The following npm versions of data-noxcqn are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate data-noxcqn if I installed it?

Remove data-noxcqn 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 data-noxcqn — how do I know if it already compromised me?

If data-noxcqn 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 data-noxcqn part of a known attack campaign?

Yes — data-noxcqn is associated with the RLMA-2025-05717 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 data-noxcqn across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for data-noxcqn (version 1.0.0).
