Hyena is a really good tool for enumerating an Active Directory network, as well as your own machine. It can show things such as:
- Drives
- Local Connections
- Users
- Local Groups
- Printers
- Shares
- Sessions
- Open Files
- Services
- Drivers
- Events Logs
- Disk Space
- User Rights
- Performance
- Scheduled Jobs
- Registry Information
- WMI Information
This can be shown for all devices under Active Directory management. This is a really useful tool for a system administrator as you can also edit settings on these devices and perform other administrative tasks.
To perform a number of the functions Hyena allows you will need to have a fairly high level of privilege on the network already. This tool is far more suited to a system administrators needs; if you have the level of privilege required for this tool, as a penetration tester, you should have a good idea already of the network's structure. That being said it may still be a useful tool to cause a little mayhem once you're in the network.
