Which versions of zzjinavcssvn are malicious?

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

How do I remediate zzjinavcssvn if I installed it?

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

If zzjinavcssvn 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.

Yes — zzjinavcssvn is associated with the RLMA-2026-04605, RLUA-2026-10543 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 zzjinavcssvn across my projects, lockfiles, and CI pipelines?
