Which versions of pthon are malicious?

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

How do I remediate pthon if I installed it?

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

If pthon 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 pthon part of a known attack campaign?

Yes — pthon is associated with the RLMA-2024-08787, funcaptcha-ru 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 pthon across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for pthon (version 1.0.0).
