Which versions of j5gnpuiwerbngpiutbgn0iutb0pfwef are malicious?

The following PyPI versions of j5gnpuiwerbngpiutbgn0iutb0pfwef are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate j5gnpuiwerbngpiutbgn0iutb0pfwef if I installed it?

Remove j5gnpuiwerbngpiutbgn0iutb0pfwef from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed j5gnpuiwerbngpiutbgn0iutb0pfwef — how do I know if it already compromised me?

If j5gnpuiwerbngpiutbgn0iutb0pfwef 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.
