Which versions of m8249v4lvd are malicious?

The following RubyGems versions of m8249v4lvd are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate m8249v4lvd if I installed it?

Remove m8249v4lvd 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 m8249v4lvd — how do I know if it already compromised me?

If m8249v4lvd 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 m8249v4lvd part of a known attack campaign?

Yes — m8249v4lvd is associated with the RLMA-2026-02709, RLUA-2026-08557 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 m8249v4lvd across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for m8249v4lvd (version 0.0.1).
