Which versions of newpackagetest2024 are malicious?

The following PyPI versions of newpackagetest2024 are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate newpackagetest2024 if I installed it?

newpackagetest2024 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 newpackagetest2024 — how do I know if it already compromised me?

If newpackagetest2024 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 newpackagetest2024 part of a known attack campaign?

Yes — newpackagetest2024 is associated with the 2023-12-valuent 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 newpackagetest2024 across my projects, lockfiles, and CI pipelines?
