Which versions of piko-fast-rb are malicious?

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

How do I remediate piko-fast-rb if I installed it?

Remove piko-fast-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 piko-fast-rb — how do I know if it already compromised me?

If piko-fast-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.
