Which versions of zzpdfvar01 are malicious?

The following RubyGems versions of zzpdfvar01 are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate zzpdfvar01 if I installed it?

Remove zzpdfvar01 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 zzpdfvar01 — how do I know if it already compromised me?

If zzpdfvar01 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 zzpdfvar01 part of a known attack campaign?

Yes — zzpdfvar01 is associated with the RLMA-2026-04609, RLUA-2026-10547 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 zzpdfvar01 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for zzpdfvar01 (version 0.0.1).
