Which versions of gauth-client are malicious?

The following PyPI versions of gauth-client are flagged malicious: 0.1.0. Treat any of these as compromised.

How do I remediate gauth-client if I installed it?

gauth-client is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed gauth-client — how do I know if it already compromised me?

If gauth-client 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 gauth-client part of a known attack campaign?

Yes — gauth-client is associated with the 2026-05-gauth-client 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 gauth-client across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for gauth-client (version 0.1.0).

Detect & block this

O3 blocks gauth-client-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
