Which versions of tiny-pro-rb are malicious?

The following RubyGems versions of tiny-pro-rb are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate tiny-pro-rb if I installed it?

Remove tiny-pro-rb 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 tiny-pro-rb — how do I know if it already compromised me?

If tiny-pro-rb 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 tiny-pro-rb part of a known attack campaign?

Yes — tiny-pro-rb is associated with the RLMA-2026-05753 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
