Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for youreallydontwantthispackage2131 (2 malicious versions).
If you installed it — respond
youreallydontwantthispackage2131 is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If youreallydontwantthispackage2131 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.
