Which versions of mt8402zmle are malicious?

The following RubyGems versions of mt8402zmle are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate mt8402zmle if I installed it?

Remove mt8402zmle 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 mt8402zmle — how do I know if it already compromised me?

If mt8402zmle 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 mt8402zmle part of a known attack campaign?

Yes — mt8402zmle is associated with the RLMA-2026-02749, RLUA-2026-08609 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 mt8402zmle across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for mt8402zmle (version 0.0.1).
