Which versions of zpx52480cs are malicious?

The following RubyGems versions of zpx52480cs are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate zpx52480cs if I installed it?

Remove zpx52480cs 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 zpx52480cs — how do I know if it already compromised me?

If zpx52480cs 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 zpx52480cs part of a known attack campaign?

Yes — zpx52480cs is associated with the RLMA-2026-04321, RLUA-2026-10259 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 zpx52480cs across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for zpx52480cs (version 0.0.1).
