Which versions of game-shuffle_cards are malicious?

The following RubyGems versions of game-shuffle_cards are flagged malicious: 1.0.5. Treat any of these as compromised.

How do I remediate game-shuffle_cards if I installed it?

Remove game-shuffle_cards 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 game-shuffle_cards — how do I know if it already compromised me?

If game-shuffle_cards 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.
