What to do

Installed one of these? Start here.

Treat the machine as compromisedUpgrading is not enough. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.

Rotate every credential that machine or CI job could reach, such as registry tokens, cloud keys, SSH keys and CI secrets, from a different machine.
Pin to a version not listed above, then reinstall from a clean lockfile.
Clear caches and private mirrors. Artifactory, Nexus, Verdaccio and devpi routinely keep serving a tarball after the public registry has pulled it.
Read the incident write-up. Recommended actions differ per incident, and some have specific indicators of compromise worth searching your logs for.
