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.

The definition states:  "Crunch is a wordlist generator where you can specify a standard character set or a character set you specify.  Crunch can generate all possible combinations and permutations."

Crunch is useful for generating wordlists and it's especially useful when you want to generate wordlists with patterns.  For example, while setting up Office365 accounts, I let the web mechanism generate passwords.  The standard generated password sets the first character as uppercase alpha, followed by two lowercase alphas, ending with a five digit number. 

The description states:  "This is a Linux box, running a WINE Application vulnerable to Buffer Overflow, escalation is pretty simple."

As stated, this is an easy buffer overflow problem assuming you understand the process.  If you want a more detailed walkthrough using a different box, my post on Brainpan, goes into greater detail for each step.
