The following RubyGems versions of wy6a903e9c are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate wy6a903e9c if I installed it?

Remove wy6a903e9c 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 wy6a903e9c — how do I know if it already compromised me?

If wy6a903e9c 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.
