How do I block Hyena

As an IT Admin, I was asked if there was a way to prevent Hyena from seeing our network should the program fall into the wrong hands. For example, a user installs Hyena on their workstation and then can see the network. Even though they may not have the credentials to actually do anything, I don't want them to see anything either. Other than not allowing users to install software via GPO, is there some other way to cripple Hyena's ability to run against a network?

thanks

Re: How do I block Hyena

Hyena uses built-in Windows functions to retrieve data, so if someone was looking for this information there are many different utilities out there (including free tools and MMC) to get the same information.

I guess the only real way to do this would be through GPO or some other method of restricting access.
