Which versions of github-orca are malicious?

How do I remediate github-orca if I installed it?

Remove github-orca 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 github-orca — how do I know if it already compromised me?

If github-orca 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.
