Which versions of @dxcl/customer-js are malicious?

The following npm versions of @dxcl/customer-js are flagged malicious: 99.99.99. Treat any of these as compromised.

How do I remediate @dxcl/customer-js if I installed it?

Remove @dxcl/customer-js 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 @dxcl/customer-js — how do I know if it already compromised me?

If @dxcl/customer-js 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 — @dxcl/customer-js is associated with the RLMA-2026-05414, RLUA-2026-05851 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 @dxcl/customer-js across my projects, lockfiles, and CI pipelines?
