How do I remediate solnetplus if I installed it?

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

If solnetplus 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 solnetplus part of a known attack campaign?

Yes — solnetplus is associated with the RLMA-2025-05581, RLMA-2026-00026 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 solnetplus across my projects, lockfiles, and CI pipelines?
