Which versions of biyndler are malicious?

The following RubyGems versions of biyndler are flagged malicious: 1.0.0, 1.0.84316. Treat any of these as compromised.

How do I remediate biyndler if I installed it?

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

If biyndler 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 biyndler part of a known attack campaign?

Yes — biyndler is associated with the RLMA-2026-07378 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
