Which versions of lang-cards are malicious?

The following RubyGems versions of lang-cards are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate lang-cards if I installed it?

Remove lang-cards 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 lang-cards — how do I know if it already compromised me?

If lang-cards 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 lang-cards part of a known attack campaign?

Yes — lang-cards is associated with the RLMA-2024-05761, RLUA-2024-10281, RLUA-2026-08368 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 lang-cards across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for lang-cards (version 1.0.0).
