What to do if you depend on any of these

Every package below was published as malicious under @tanstack. Treat any machine that installed one as compromised: remove the package and its lockfile entry, rotate every credential the build or runtime could reach (registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values) from a known-clean machine, and audit for unexpected outbound activity.

Because the packages share a publisher scope, a project that pulled in one has an elevated chance of having pulled in others. Search your lockfiles for @tanstack rather than checking a single package name.
