Which versions of ztrivial001 are malicious?

The following RubyGems versions of ztrivial001 are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate ztrivial001 if I installed it?

Remove ztrivial001 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 ztrivial001 — how do I know if it already compromised me?

If ztrivial001 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 ztrivial001 part of a known attack campaign?

Yes — ztrivial001 is associated with the RLMA-2026-04463, RLUA-2026-10401 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 ztrivial001 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for ztrivial001 (version 0.0.1).

Detect & block this

O3 blocks ztrivial001-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
