Which versions of pypi-package-explore are malicious?

The following PyPI versions of pypi-package-explore are flagged malicious: 0.0.1a0, 0.0.2a0, 0.0.3a0, 0.0.4a1, 0.0.4a2, 0.0.4a3, 0.0.4a4. Treat any of these as compromised.

How do I remediate pypi-package-explore if I installed it?

pypi-package-explore 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 pypi-package-explore — how do I know if it already compromised me?

If pypi-package-explore 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 pypi-package-explore part of a known attack campaign?

Yes — pypi-package-explore is associated with the 2026-01-pypi-package-explore campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
