Which versions of ebay-client are malicious?

The following RubyGems versions of ebay-client are flagged malicious: 0.3.1.1045. Treat any of these as compromised.

How do I remediate ebay-client if I installed it?

Remove ebay-client 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 ebay-client — how do I know if it already compromised me?

If ebay-client 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 ebay-client part of a known attack campaign?

Yes — ebay-client is associated with the RLMA-2024-05685, RLUA-2024-10204, RLUA-2026-08028 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 ebay-client across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for ebay-client (version 0.3.1.1045).
