## What to do if you installed one of these

1. Treat the machine as compromised rather than simply upgrading. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.
2. Rotate every credential that machine or CI job could reach - registry tokens, cloud keys, SSH keys, CI secrets - from a *different* machine.
3. Pin to a version not listed above, then reinstall from a clean lockfile.
4. Clear caches and private mirrors. Artifactory, Nexus, Verdaccio, and devpi routinely keep serving a tarball after the public registry has pulled it.
5. Read the incident write-up linked above - recommended actions differ per incident, and some have specific indicators of compromise worth grepping your logs for.
