Which versions of spectral-module are malicious?

The following npm versions of spectral-module are flagged malicious: 99.0.0. Treat any of these as compromised.

How do I remediate spectral-module if I installed it?

Remove spectral-module 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 spectral-module — how do I know if it already compromised me?

If spectral-module 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 spectral-module part of a known attack campaign?

Yes — spectral-module is associated with the RLMA-2026-01817 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 spectral-module across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for spectral-module (version 99.0.0).
