Which versions of vspropertypages are malicious?

The following NuGet versions of vspropertypages are flagged malicious: 99.99.99. Treat any of these as compromised.

How do I remediate vspropertypages if I installed it?

Remove vspropertypages 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 vspropertypages — how do I know if it already compromised me?

If vspropertypages 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.
