The following RubyGems versions of zpx52554yg are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate zpx52554yg if I installed it?

Remove zpx52554yg 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 zpx52554yg — how do I know if it already compromised me?

If zpx52554yg 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.

How do I find zpx52554yg across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for zpx52554yg (version 0.0.1).
