Which versions of veilcord-tls are malicious?

The following PyPI versions of veilcord-tls are flagged malicious: 0.0.7.5, 0.0.7.6. Treat any of these as compromised.

How do I remediate veilcord-tls if I installed it?

Remove veilcord-tls 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 veilcord-tls — how do I know if it already compromised me?

If veilcord-tls 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.
