Which versions of smm-yt are malicious?

The following npm versions of smm-yt are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate smm-yt if I installed it?

Remove smm-yt 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 smm-yt — how do I know if it already compromised me?

If smm-yt 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.

Is smm-yt part of a known attack campaign?

Yes — smm-yt is associated with the RLMA-2026-01580 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 smm-yt across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for smm-yt (version 1.0.0).
