Which versions of network-utils-simple are malicious?

The following PyPI versions of network-utils-simple are flagged malicious: 1.0.0, 1.1.0, 1.2.1, 1.2.2, 1.2.3, 1.2.4, 1.2.5, 1.2.6, 1.2.7, 1.2.8, 1.2.9, 1.3.0, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 1.3.6, 1.3.7, 1.3.8. Treat any of these as compromised.

How do I remediate network-utils-simple if I installed it?

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

If network-utils-simple 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 network-utils-simple part of a known attack campaign?

Yes — network-utils-simple is associated with the 2025-02-network-utils-simple campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
