Which versions of @cashback/auth are malicious?

The following npm versions of @cashback/auth are flagged malicious: 99.9.9. Treat any of these as compromised.

How do I remediate @cashback/auth if I installed it?

Remove @cashback/auth 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 @cashback/auth — how do I know if it already compromised me?

If @cashback/auth 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.

Yes — @cashback/auth is associated with the RLMA-2026-04696, RLUA-2026-05837 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @cashback/auth across my projects, lockfiles, and CI pipelines?
