Which versions of @azure-lab-services/ml-ts are malicious?

The following npm versions of @azure-lab-services/ml-ts are flagged malicious: 99.0.0. Treat any of these as compromised.

How do I remediate @azure-lab-services/ml-ts if I installed it?

Remove @azure-lab-services/ml-ts 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 @azure-lab-services/ml-ts — how do I know if it already compromised me?

If @azure-lab-services/ml-ts 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 — @azure-lab-services/ml-ts is associated with the RLMA-2026-05401, RLUA-2026-05823 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 @azure-lab-services/ml-ts across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for @azure-lab-services/ml-ts (version 99.0.0).
