Which versions of synapseml-utils are malicious?

The following PyPI versions of synapseml-utils are flagged malicious: 0.1.0, 0.1.1, 0.1.2, 0.1.3, 0.1.4, 0.1.5. Treat any of these as compromised.

How do I remediate synapseml-utils if I installed it?

synapseml-utils 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 synapseml-utils — how do I know if it already compromised me?

If synapseml-utils 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 synapseml-utils part of a known attack campaign?

Yes — synapseml-utils is associated with the 2026-03-synapseml-utils 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 synapseml-utils across my projects, lockfiles, and CI pipelines?
