Which versions of puffioner131 are malicious?

The following PyPI versions of puffioner131 are flagged malicious: 9999, 99999, 999999, 9999999, 99999999, 999999991, 999999999. Treat any of these as compromised.

How do I remediate puffioner131 if I installed it?

puffioner131 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 puffioner131 — how do I know if it already compromised me?

If puffioner131 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 puffioner131 part of a known attack campaign?

Yes — puffioner131 is associated with the GENERIC-standard-pypi-install-pentest campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
