Which versions of em_statsd-ruby are malicious?

The following RubyGems versions of em_statsd-ruby are flagged malicious: 1.0.3. Treat any of these as compromised.

How do I remediate em_statsd-ruby if I installed it?

Remove em_statsd-ruby 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 em_statsd-ruby — how do I know if it already compromised me?

If em_statsd-ruby 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 em_statsd-ruby part of a known attack campaign?

Yes — em_statsd-ruby is associated with the RLMA-2024-05693, RLUA-2024-10212, RLUA-2026-08050 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 em_statsd-ruby across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for em_statsd-ruby (version 1.0.3).
