How do I remediate ldhemrdhs92004 if I installed it?

Remove ldhemrdhs92004 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 ldhemrdhs92004 — how do I know if it already compromised me?

If ldhemrdhs92004 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 — ldhemrdhs92004 is associated with the RLMA-2025-05835 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
