Which versions of zw_dl_ics are malicious?

The following RubyGems versions of zw_dl_ics are flagged malicious: 0.0.1340. Treat any of these as compromised.

How do I remediate zw_dl_ics if I installed it?

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

If zw_dl_ics 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 zw_dl_ics part of a known attack campaign?

Yes — zw_dl_ics is associated with the RLMA-2026-04469, RLUA-2026-10407 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 zw_dl_ics across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for zw_dl_ics (version 0.0.1340).
