Which versions of alembic-util are malicious?

The following PyPI versions of alembic-util are flagged malicious: 0.189.33. Treat any of these as compromised.

How do I remediate alembic-util if I installed it?

alembic-util 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 alembic-util — how do I know if it already compromised me?

If alembic-util 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 alembic-util part of a known attack campaign?

Yes — alembic-util is associated with the 2025-06-alembic-util 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 alembic-util across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for alembic-util (version 0.189.33).
