Which versions of rxlws are malicious?

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

How do I remediate rxlws if I installed it?

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

If rxlws 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 rxlws part of a known attack campaign?

Yes — rxlws is associated with the RLMA-2026-03200, RLUA-2026-09094 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 rxlws across my projects, lockfiles, and CI pipelines?

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