Another cyber range appeared recently and it's similar to Vulnhub where people upload VM's, you download them, and get flags.  There's a points system like TryHackMe and HackTheBox which is a great way to gamify the environment.  I was curious to play and I download Number. 

The box does not have a description other than it states that it's a Medium level system.

From the description:  "Remote Server Administration Tools (RSAT) lets IT admins manage Windows Server roles and features from a Windows 10 PC."

RSAT can be used to enumerate the domain from any Windows 10 workstation (probably lower versions too) as long as it's either already installed already or you have local admin access.  I wrote this collection of commands to replace PowerView because outside of lab environments, PowerView won't make it onto the machine without endpoint protection eating it. 

The description for BadBlood states:  "It is a security tool for Active Directory. Run BadBlood on a domain so that security analysts and engineers can practice using tools to gain an understanding and prescribe to securing Active Directory.  Each time this tool runs, it produces different results. The domain, users, groups, computers and permissions are different."

I think that pretty much sums it up and the point is that we don't often get to work on large test environments and this creates large, unique, environments, that we can use to hone our craft.
