Which versions of m8320v2umh are malicious?

The following RubyGems versions of m8320v2umh are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate m8320v2umh if I installed it?

Remove m8320v2umh 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 m8320v2umh — how do I know if it already compromised me?

If m8320v2umh 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 m8320v2umh part of a known attack campaign?

Yes — m8320v2umh is associated with the RLMA-2026-02713, RLUA-2026-08561 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 m8320v2umh across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for m8320v2umh (version 0.0.1).
