Which versions of banner-jobsub are malicious?

The following RubyGems versions of banner-jobsub are flagged malicious: 0.1.2. Treat any of these as compromised.

How do I remediate banner-jobsub if I installed it?

Remove banner-jobsub 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 banner-jobsub — how do I know if it already compromised me?

If banner-jobsub 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.
