Which versions of sm8225hxzu are malicious?

The following RubyGems versions of sm8225hxzu are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate sm8225hxzu if I installed it?

Remove sm8225hxzu 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 sm8225hxzu — how do I know if it already compromised me?

If sm8225hxzu 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.

Yes — sm8225hxzu is associated with the RLMA-2026-03456, RLUA-2026-09354 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 sm8225hxzu across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for sm8225hxzu (version 0.0.1).
